SUBJECT:
DELUGE, PRE-ACTION AND FOAM-WATER DELUGE S PRINKLER*
- SYSTEMS:
MODEL C DELUGE VALVES CD se Gentlemen:
We have become aware of a potential problem which may affect the fire protection sprinkler system in your building or property.
I f the problem exists, IT MAY PREVENT 'IME SPRINKLER SYSTEM FROM OPERATING IN THE EVENT OF A FIRE.
The following outlines:
A.
The nature of the problem, B.
How to identify whether your system is a f fe cted,
C.
Required course of action.
A.
THE NATURE OF THE PROBLEM We have discovered several 6" valves that failed to trip properly even a fter being serviced within the last s ix to twelve months.
The valves stuck inside where the latch touches the valve clapper.
We believe that the following factors contributed to the problem.
1.
Relatively high water pressure, (over 100 psi),
2.
Corrosive atmosphere, 3.
Inadequate trip test procedures.
Please note that we may have ' reviously notified you late last p
year or early this year about this valve.
At that time we recommended a maintenance procedure which has since proven inadequate.
If your system is of the serial numbers re ferenced below, follow this new procedure.
The corrective action provided by this letter is regarded as a TEMPORARY SOLUTION, but one which should be implemented IMMEDIATELY.
We are preparing a final solution and will notify you when it is available.
It is our current intent to have this final solution available by April 1986.
Although the problem encountered has only been found in 6" Model C valves, we are applying this corrective action to both the 2-1/2" and 6" sizes.
The valves involved in the immediate corrective action recommended by this letter are those manu factured since 1973.

0 MODEL C DELUGE VALVES December 12, 1985 Page 2 B.
HOW TO IDENTIFY WHETHER YOUR MODEL C SYSTEM MAY BE AFFECTED Model C deluge valves are installed in Rate-of-Rise Sprinkler Systems and in Pilot Head Sprinkler Systems.
The systems are further subdivided into Deluge Sprinkler Systems, Pre-Action Sprinkler Systems or Foam-Water Deluge Sprinkler Sys tems.
The valves are also identified as " Deluge", "Suprotex",
" Pre-Action", "Suprotex-Deluge", and "Suprotex/ Pre-Action".
In Foam-Water deluge systems, both the water deluge valve and the foam deluge valve may be Model C deluge valves.
The Model C deluge valve has also been installed by Grinnell under the name "Multitrol".
Serial numbers a f fected are:
2-1/2" Model C Deluge Valve :
S/N S4,026 through S10,250 (Excluding SN S10244, S10245, and S10246) 6" Model C Deluge Valve:
S/N S6,024 through S12,350 Each Model C valve is identified by a serial number stamped into the front edge of the upper flange and by the lettering "Model C" cast in raised letters on the back of the valve.
C.
REQUIRED COURSE OF ACTION Your present inspection procedure may not detect a potential mal function; there fore, we strongly recommend that you have a competent technician follow the procedure given below.
At the earliest possible opportunity, the following procedure should be performed on the 2-1/2" and 6" valves in the seri.al number ranges given above.
A molybdenum disul fide lubricant, 813MS, is required by thi s procedure.
It can be obtained at no charge by calling the Quality Assurance Manager, " Automatic" Sprinkler Corporation at (216) 526-9900 or 1-800-ASCOA US or your local " Automatic" Sprinkler Office (see attached phone list).
You may also obtain this lubricant by sending a telex request (telex no. 822054) giving the name and address of the location and the name of the person to Whom the lubricant is to be sent.
Please provide the serial numbers of the valves at your facilities a f fected by this letter.
When each valve is serviced in accordance Sith the procedures given below, please observe appropriate precautions with respect to any electrical devices connected to the system.
Make sure that the valve under test will not trip other valves.

Use a competent technician.
These systems require specialized knowledge and should not be tampered with by inexperienced personnel.
2.
Shut off the OS & Y control valve and open the main drain valve to remove any pressure from the under-side of the clapper.
Release the weight by pulling the manual release nechanism.
Remove the hand hole cover.
Remove the clapper.
3.
Inspect the clapper and latch mating sur faces.
These sur faces must be smooth.
Re finish the sur faces using 220 grit sandpaper followed by crocus cloth to obtain a smooth finish on both sur faces.
4.
Clean the two sur faces with lacquer thinner and allow the sur faces to dry.
5.
Apply a thin coating of 813MS lubricant to both the clapper and latch sur faces.
6.
Inspect the clapper facing, seat ring and valve interior in accordance with applicable Care and Maintenance Instructions.
7.
Reassemble the valve, reset the weight, then s
replace the hand hole cover.
Slowly open the OS & Y contrcl valve until water begins to flow from the main drain.
Slowly close the drain.
8.
Open the OS & Y control valve completely.
If the protected facility can sa fely conduct a partial flow test, it is recommended that a partial flow test be per fo rmed as fbilows :
9.
Adjust the OS & Y control valve to the nearly closed position (open about 1 turn from fully closed).
Release the weight by pulling on the manual release handle.
The clapper, under full water pressure, should open.
Immediately close the OS & Y control valve.
Open the drain valve to drain the system piping.

The fire brigade arrived to find that the automatic deluge valve had not opened.
The manual release failed to open the valve. A mechanic opened the actuator box cover and struck the actuation weight, forcing the clapper latch to release, permitting water spray from the sprinkler system to extinguish the fire.
(See Attachaient 1. ) The valve was a 6-inch Model C, manufactured by Automatic Sprinkler Corporation of America of Cleveland, Ohio.
(Reference LER 50-416/83-126.)
During subsequent testing and examination, excessive friction was noted between the weight and the weight guide rod; bowing (0.005-inch) was observed in the weight guide rod; evidence of scoring was found in two locations on the rod's j
surface; the weight's upper guide collar had an inside diameter (ID) of 0.637 j
inch rather than the manufacturer's recommended minimum of 0.647 inch; and scoring was noted on the enclosing box along the path that the weight guide bushing traces during actuation.
On December 5,1983, a Model C valve for a pre action sprinkler system pro-tecting a diesel generator room failed to operate during a test at Grand Gulf.

\\
another event at Grand Gulf in which a Model C valve installed to protect a main transformer failed to open during a test in September 1979.
The valve manufacturer has been notified of these failures and is evaluating this problem to determine the action required.
The licensee's preliminary investigation indicates that these failures may be related to the surface condition of the latch which holds the water clapper in the normally closed position.
If the mating surfaces of the latch and clapper are not smooth, the latch may fail to disengage when the actuation weight hits the latch arm.
If the normal water system pressure applied to the clapper valve exceeds 140 psig, the problem becomes more acute.
The water pressure at Grand Gulf is maintained at 140 psig.
MP&L has sanded and trued the guide rod; reworked the ID of the weight's upper guide collar; lubricated the rod, latch pin, clapper hirrge pin, and the en-closed box along the path of the weight guide bushings; temporarily increased the testing frequency of the valves; and revised the surveillance procedures to visually verify that the clapper has lifted and locked open following the test under normal system pressure.
If you have any questions regarding this matter, contact the Regional Administrator of the appropriate NRC Regional Office, or this office.

FAILURE OF AUTOMATIC SPRINKLER SYSTEM VALVES TO OPERATE Addressees:
All nuclear power reactor facilities holding an operating license (OL) or a construction permit (CP).
Purcose:
This information notice provides notification of a problem involving the operational failure of deluge and pre-action fire protection water control valves, identified as Model C, manufactured by Automatic Sprinkler Corporation of America of Cleveland, Ohio.
It is expected that recipients will review this information notice for applicability to their facilities.
No specific action or response is required.
Descriotion of Circumstances:
On September 4,1983, Mississippi Power and Light (MP&L) Ccmpany's Grand Gulf Unit 1 was performing an operational test of an emergency dietel generator when a fire involving the diesel engine occurred.
The fire brigade arrived to find that the automatic deluge valve had not opened.
The manual release failed to open the valve.
A mechanic opened the actuator box cover and struck the actuation weight, forcing the clapper latch to release, permitting water spray from the sprinkler system to extinguish the fire.
(See Attachment 1.) The valve was a 6-inch Model C, manufactured by Automatic Sprinkler Corporation of America of Cleveland, Ohio.
(Reference LER 50-416/83-126.)
During subsequent testing and examination, excessive friction was noted between the weight and the weight guide rod; bowing (0.005-inch) was observed in the weight guide rod; evidence of scoring was found in two locations on the rod's surface; the weight's upner guide collar had an inside diameter (ID) of 0.637 inch rather than the manufacturer's recommended mi~nimum of 0.647 inch; and scoring was noted on the enclosing box along the path that the weight guide bushing traces during actuation.
On December 5,1983, a Model C valve for a pre-action sprinkler system pro-tecting a diesel generator room failed to operate during a test at Grand Gulf.
Similar roughness was found in its internals.

If the normal water system pressure applied to the clapper valve exceeds 140 psig, the problem becomes more acute.
The water pressure at Grand Gulf is maintained at 140 psig.
MP&L has sanded and trued the guide rod; reworked the ID of the weight's upper guide collar; lubricated the rod, latch pin, clapper hinge pin, and the en-closed box along the path of the weight guide bushings; temporarily increased the testing frequency of the valves; and revised the surveillance procedures to visually verify that the clapper has lifted and locked open following the test under normal system pressure.

Nuclear Regulatory Consnission Information Notice 84-16,
" Failure of Automatic Sprinkler System Valves to Operate"
Dear Mr. DeYoung:
The following information is provided in response to the Nuclear Regulatory Commission Infomation Notice 84-16 concerning operational failures of our Model C deluge valve at Grand Gulf Unit No.1 of the Mississippi Power and Light Company.
To.obtain an indication of whether this problem existed at other installations, we tested a total of seventeen (17) 2-1/2" Model C deluge valves at eight (8) different locations and eight (8) 6" Model C deluge valves at three (3) different locations, using a special test procedure (130.002SP), ar.d found no operational failures. Two (2) additional six inch (6") Model C deluge valves were tested at a fourth location without failure using the standard-test procedure.
The special test procedure required the weight on each valve to be dropped only one-half
~'
the normal distance so that only one-half the energy is generated to unlatch the valve under this special test condition. A tabulation of the 2-1/2" and 6" valves tested is given on Table I.
The results of our field tests do not indicate a problem with our valve design or manufacture.
We performed a number of tests in our laboratory on a 6" Model C deluge valve and found we could duplicate the type of operational failure experienced at the Grand Gulf facility if the latch and clapper nose mating surfaces'were rough (approximately a 500 microinch finish or rougher).
We reviewed our drawings to determine if any changes were made which could have caused the problem observed at the Grand Gulf facility. A drawing change was made in September of 1973 which changed the finish requirement on the clapper and latch mating surfaces from a 63 microinch to a 125 microinch finish.
Valves with serial numbers higher than 4586 for 2-1/2" valves and 6821 for 6"' valves were manufactured after the September 1973 drawing change and, since the Grand Gulf Unit No.1 valve serial numbers were higher than those identifying the 1973 finish change, we required that the valves tested in the field to our special test procedure have serial numbers which indicate that they were produced after the surface finish change.. As pre-viously stated, no operational failures were found on the valves tested which were produced after the surface finish change.
l Although we did not find the Grand Gulf mode of failure at any other installation, we made two changes to increase the probability of successful valve operation. The surface Su Mi n e x q g...,~,,.-........ en..n.., ~ n......-.

l finish drawing requirement of the clapper nose and latch mating surfaces was changed from a 125 microinch finish to a 16 microinch finish on November 1983, and our data pages G8a and G22a (copies enclosed) were changed to require refinishing of the clapper nose i
and latch mating surfaces at each routine, periodic inspection.
With respect to the conditions noted in Information Notice No. 84-16 regarding bowing of the guide rod and the undersize I.D. of the upper guide rod collar, the following information is offered.
The guide rod we install in our valves is purchased under ASTM B16, material C36000.
The ASTM B16 (Table 15) straightness requirement is 1/32" maximum curvature (depth of arc) in any 2 ft long portion. The bowing observed (0.005 inch) in the 20 inch long guide rod used in our 6" Model C deluge valve easily meets the ASTM requirement.
The upper guide collar was stated to have an I.D. of 0.637 inch and our minimum I.D.
' dimension was stated to be 0.647 inch. Our actual drawing minimum dimension for this I.D. is 0.640 so the collar was measured by the Grand Gulf people to be undersize by 0.003 inches.
However, the ASTM B16 requirement for the guide rod is 0.625 0.002".
The minimum clearance for the guide rod in this undersize hole is 0.637-0.627 or 0.010 inches which is adequate to allow the weight to slide freely on the guide rod even if the guide collar I.D. was undersize as claimed.
It is our conclusion that no design or manufacturing fault exists in our Model C deluge valves; however, we revised the maintenance procedure and require smoother surfaces in manufacturing to increase the probability of successful operation of both new and existing Model C deluge valves.
We further conclude the operational failures at Grand Gulf Unit #1 are peculiar to that facility.

' dimension was stated to be 0.647 inch. Our actual drawing minimum dimension for this I.D. is 0.640 so the collar was measured by the Grand Gulf people to be undersize by 0.003 inches.
However, the ASTM B16 requirement for the guide rod is 0.625 0.002".
The minimum clearance for the guide rod in this undersize hole is 0.637-0.627 or 0.010 inches which is adequate to allow the weight to slide freely on the guide rod even if the guide collar I.D. was undersize as claimed.
It is our conclusion that no design or manufacturing fault exists in our Model C deluge valves; however, we revised the maintenance procedure and require smoother surfaces in manufacturing to increase the probability of successful operation of both new and existing Model C deluge valves.
We further conclude the operational failures at Grand Gulf Unit #1 are peculiar to that facility.

" Failure of Automatic Sprinkler System Yalves to Operate" i
Dear Mr. DeYoung:
The following information is provided in respouse to the Nuclear Regulatory Commission Infomation Notice 84-16 concerning operational failures of our Model C deluge valve at Grand Gulf Unit No.1 of the Mississippi Power and Light Company.
To obtain an indication of whether this problem existed at other installations, we tested a total of seventeen (17) 2-1/2" Model C deluge valves at eight (8) different locations and eight (8) 6" Model C deluge valves at three (3) different locations, u:,ing a special test procedure (130.002SP), and found no operational failures.
Two (2) additional six inch (6") Model C deluge valves were tested at a fourth location without failure using the standard test procedure.
The special test procedure required the weight on each valve to be dropped only one-half the normal distance so that only ene-half the energy is generated to unlatch the valve under this special test condition.
A tabulation of the 2-1/2" and 6" valves tested is given on Table I.
The results of our field tests do not indicate a problem with our valve design or manufacture.
We perfomed a number of tests in our laboratory on a 6" Model C deluge valve and found we could duplicate the type of operational failure experienced at the G.and Gulf facility if the latch and clapper nose mating surfaces ~ were rough (approximately a 500 microinch finish or rougher).
We reviewed our drawings to determine if any changes were made which could have caused the problem observed at the Grand Gulf facility. A drawing change was made in September of 1973 which changed the finish requirement on the clapper and latch mating surfaces from a 63 microinch to a 125 microinch finish.
Valves with serial numbers higher than 4586 for 2-1/2" valves and 6821 for 6" valves were manufactured after the September 1WTdrawing change and, since the Grand Gulf Unit No.1 valve serial numbers were higher than those identifying the 1973 finish change, we required that the valves tested in the field to our special test procedure have. serial numbers which indicate that they were produced after the surface finish change.. As pre-viously stated, no operational failures were found on the valves tested which were produced after the surface finish change.
Although we did not find the Grand Gulf mode of failure at any other installation, we made two char:ges to increase the probability of successful valve operation.

We have become aware of a potential problem which may affect the fire protection sprinkler system in your building or property. If the proble exists, IT MAY PREVENT 'IHE SPRINKLER SYSTm FROM OPERATING IN 'IHE EVD7f OF A FIRE. 'Ihe following outlines:
A.
'Ihe nature of the problem, B.
How to identify whether a system may be affected, C.
Recomended course of action.
A.
N NA'IURE-OFTHE-PPOBLEM Within the last year we have had three reported instances, involving seven valves, in which 6" Model C deluge valves failed to trip when full water pressure was applied to the valve. It appears that the impact of the release weight (item 22 on the attached drawing G-14) was not sufficient to disengage the latch (item 12) frcm the clapper (item 6) under certain time, pressure and water conditions.
All three reported failures occurred in the 6" Model C deluge valve size, operating under relatively high pressure, (over 100 psi) and installed.for over 6 years. It is felt that the roughness of the two mating surfaces, the clapper nose and latch, may change enough to prevent opening because of increased starting friction. However, we have been unable to ascertain precisely what conditions cause the change in surface roughness in the isolated cases reported to date.
We do know that all valves have been factory tested before shipment.
'Ihis test is at high (200 psi) and medium (50-75 psi) pressure.
We further caution you that this condition may not be evident.
Superficial inspections may not satisfactorily duplicate actual fire conditions. You may think your valve would work when in fact it would not. Your system's actual pressure may be greater (over 100 psi) when a fire pump is operating than when in the static condition.
Since your present inspection procedure may not detect a potential malfunction, we strongly reccanend that you have a cmpetent mechanic follow the below untioned procedure. Where we have encountered the problen, this relatively simple procedure has restored the valves to proper working order.

fDPID-IDENPIPEhemeYOUR SYMMAY-BEXtum Model C deluge valves are installed in Rate-of-Rise Sprinkler Systems and in Pilot Head Sprinkler Systems. %e systems are further subdivided into Deluge Sprinkler Systems, Pre-Action Sprinkler Systems or Foam-Water Deluge Sprinkler Systems.
he valves are also identified as " Deluge","Suprotex"," Pre-Action",
"Suprotex-Deluge", and "Suprotex/ Pre-Action". In Foam-Water deluge systems, both the water deluge valve and the foam deluge valve may be Model C deluge valves.
%e Model C deluge valve has also been installed by Grinnell under the name "Multitrol" and by Rockwocd Sprinkler Canpany under the name "Dualguard".
C.
REEMMBOEIMYURSBOP-MPION We recm mend that at the earliest possible opportunity, the following procedure be followed and REPEATED ON AN ANWAL BASIS:
1.
Use a competent mechanic. W ese systems often require specialized knowledge and should not be tampered with by inexperienced personnel.-
2.
Determine if the protected facility can safely conchct a partial flow test. If it can, conduct t.he procedure outlined in the next pergraph.
3.
Adjust the OS & Y control valve to the nearly closed position (open about 3/4 to 1 turn from fully closed).
Remove the enclosing box cover and grasp the weight firmly. Release the weight by pulling on the manual release handle. Iower the weight on a 6" Model C valve to 4" - 41/2" below its latched position. On a 2 1/2" Model C valve, lower the weight to 2" - 2 1/2" below its latched position. Allow the weight to freely drop on the latch arm. % e clapper, under full water pressure should open. Inmediately close the OS & Y 1
control valve. Open the drain valve to drain the system piping. If the valve tripped, reset the valve in accordance with the applicable procedure (see instruction for Care and Maintenance), setting the system back into operation.
4.
If the system fails to trip, please notify the Quality Assurance Manager, " Automatic" Sprinkler Corporation of America at (216) 526-9900. We are most interested in identifying and assisting you in resolving any problems which may arise.

If a partial flow test cannot be conducted, perform the following maintenance procedure.
6.
Shut off the OS & Y control valve and open the drain valve to remove any pressure fr m ths. underside of the clapper. Renove the enclosing but cover. Release the weight by pulling the manual release mechanism. Remove the hand hole cover. Remove the clapper.
7.
Inspect the cla mer and latch nating surfaces. 'Ihese surfaces must be smooth. Refinish the surfaces using 220 grit sandpaper followed by crocus cloth to obtain a smooth finish on both surfaces.
8.
Inspect the clapper facing, seat ring and vnive interior in accordance with applicable Care and Maintenance Procedure.
9.
Reassernble the valve. Reset the weight. Slowly open the OS & Y control valve until water begins to flow fre. the drain. Slowly close the drain. Fully open the OS & Y control valve, setting the systen back into operation.
Wile we have identified only seven Model C deluge valve malfunctions out of an estimated 75,000 valves installed since 1931, we feel it is our obligation to notify you of this potential problem. Conducting the maintenance procedure is your choice. We strongly reconmend you do so.

SUBJECT:
DELUGE, PRE-ACTION AND FOAM-WATER DELUGE SPRINKLER SYSTEMS; MODEL C DELU3E VALVES Gentle:nen:
We have become aware of a potential problem which may affect the fire protection sprinkler system in your building or property.
If the problen exists, IT MAY PRE PJr 'IEE SPRINKLER SYSTEM FROM OPERATIN3 IN EE EVE 27f OF A FIRE. 'Ibe V
following outlines:
A.
'Ihe nature of the problem, B.
How to identify whether a system may be affected, C.
Recommended course of action.
A.
NE-tW"of-OME-PPOBL91 Within the last year we have had three reported instances, involving seven valves, in which 6" Model C deluge valves failed to trip when full water pressure was applied to the valve. It appears that the ir: pact of the release weight (ite:a 22 on the attached drawing G-14) was not sufficient to disengage the latch (item 12) frcxn the clapper (item 6) under certain time, pressure and water conditions.
All three reported failures occurred in the 6" Model C deluge valve size, operating under relatively high pressure, (over 100 psi) and installed.for over 6 years.
It is felt that the roughness of the two mating surfaces, the clapper nose and latch, may change enough to prevent opening because of increased starting friction. However, we have been unable to ascertain precisely what conditions cause the change in surface roughness in the isolated cases reported to date.
We do know that all valves have been factory tested before shipment.
'Ihis test is at high (200 psi) and medium (50-75 psi) pressure.
We further cauticn you that this condition may not be evident.
Superficial inspections may not satisfactorily duplicate actual fire conditions.
You may think your valve would work when in fact it would not. Your system's actual pressure may be greater (over 100 psi) Wen a fire pump is operating than when in the static condition.
Since your present inspection procedure may not detect a potential n'alfunction, we strongly reccrimend that you have a competent mechanic follow the below mentioned procedure.
Where we have encountered the problen, this relatively simple procedure has restored the valves to proper working order.

f!OR 'ID--IDENPIFY-wrmm-YOUR-@l9f'Dt-MAY-BE-Mrrurm Model C deluge valves are installed in Rate-of-Rise Sprinkler Systems and in Pilot Head Sprinkler Systems. S e systems are further subdivided into Deluge Sprinkler Systems, Pre-Action Sprinkler Systems or Foam 4 tater Deluge Sprinkler Systems.
he valves are also identified as " Deluge","Suprotex"," Pre-Acticn",
I "Suprotex-Deluge", and "Suprotex/ Pre-Action". In Foam-Water deluge systems, i
both the water deluge valve and the foam deluge valve may be Model C deluge valves.
h e Model C deluge valve has also been installed by Grinnell under the name "Multitrol" and by Rockwood Sprinkler Company under the name "Dualguard".
C.
RE00 MENDED-CotPSEMP-AC'I' ION We recommend that at the earliest possible opportunity, the following procedure be followed and REPEATED ON AN ANNUAL BASIS:
1.
Use a competent r.echanic.
These systems often require specialized knowledge and should not be tampered with t
by inexperienced personnel.-
2.
Determine if the protected facility can safely conduct a partial flow test.
If it can, conduct the procedure outlined in the next pargraph.
3.
Adjust the OS & Y control valve to the nearly closed position (open about 3/4 to 1 turn from fully closed).
Remove the enclosing box cover and grasp the weight i
firmly. Release the weight by pulling on the manual j
release handle. Lower the weight on a 6" Model C valve to 4" - 41/2" below its latched position. On a 2 1/2" l
Model C valve, lower the weight to 2" - 2 1/2" below i
its latched position. Allow the weight to freely drop on the latch arm. S e ela w, under full water
{
pressure should open. Inmediately close the OS & Y oontrol valve. Open the drain valve to drain the system piping. If the valve tripped, reset the valve in accordance with the applicable pc~=^'re (see in::tscLion for Care and Maintenance), setting the system back into operation.
i 4.
If the system fails to trip, please notify the Quality Assurance Manager, "Auttnatic" Sprinkler Corporation of America at (216) 526-9900. We are most interested in identifying and assisting you in resolving any problems which may arise.

If a partial f1w test cannot be concheted, perform the' follwing maintenance prMre.
6.
Shut off the OS & Y control valve and open the drain 1
valve to renove any pressure from the underside of the clapper. Remove the enclosing box cover. Release the weight by pulling the manual release mechanisrc. Remove the hand hole cover. Remove the clapper.
7.
Inspect the clapper and latch mating surfaces. 'Jhese surfaces must be smooth. Refinish the surfaces using 220 grit sandpaper foll wed by crocus cloth to obtain a smooth finish an both surfaces.
8.
Inspect the clapper facing, seat ring and valve interior in accordance with applicable Care and Maintenance Procedure.
9.
Reassemble the valve. Reset the weight. Slowly open the OS & Y control valve until water begins to flow frm the drain. Slowly close the drain. Fully open the OS & Y control valve, setting the systen back into operation.
htile we have identified only seven Model C deluge valve malfunctions out of an estirated 75,000 valves installed since 1931, we feel it is our obligation to notify you of this potential problem.
Conducting the maintenance procedure is your choice. We strongly reccamend you do so.

A.
THE G3UPE OF THE PPDAJ CM Within the last year we have had three reprted instanms, imolding seven valves, in which 6" mdel C deluge valves failed to trip when full water gessure was applied to the valve.
It appears that the impct of the releam weight (item 22 on the attached drzwing G-14) was not sufficient to dimngage the latch (iten 12) fran the clapper (itan 6) unchr mrtain time, gessure and water conditions.
All three reprted failures occurred in the 6" Mochl C deluge valve size, operating mder relatively high gessure, (cver 100 psi) and installed for over 6 years.
It is felt that the roughness of the two mating surfa s, the clatter nose and latch, may change enough to gevent opening because of increased starting frictico.
Scwever, we have been unable to aswrt:aln Erecisely what conditions cause the cinnge in surface roughness in the isolated cases reported to chte.
We cb kncw that all valves have been factory tested before rhipnent.
'Ihis test is at high (200 psi) and medium (50-75 psi) pressure.
We further caution you that this condition may not be evident. Superficial inspections may not satisfactorily duplicate actual fire conditions. You may think your valve would work when in fact it would not. Your systom's actml Fensure may be greater (over 100 psi) when a fire punp is operating than when in the static condition.
Since your gesent inspectico gocechre may not detect a ptential calfunction, we strongly recamend that you have a congtent mechanic follcw the below nenticned promchre. Where we have encomtered the Fablen, this relatively nimple go dure has restored the valves to goper working order.

Renove the enclosing box cover and grasp the wei@t firmly. Release the weight by pulling on the manual release handle.
Iower the weight on a 6" Model C valve to 4" - 41/2" belw its latched position. On a 21/2" mdal C valve, lower the weicht to 2" - 21/2" belev its latched psition. Allow the wei@t to freely clop on the latch aan. %e clapper, mder full water gessure should open.
Innediately close the N & Y control valve. Open the drain valve to drain the systan piping.
If the valve tripped, reset the valve in accorchnee with the applicable gocechre (see instruction for Chre and Maintenance), setting the systen tack into operation.

MODP.L C DELUGE VALVES Gentlemen:
We have become aware of a potential problem which may affect the fire protection sprinkler system in your building or property.
I f the problem exists, IT MAY PREVENT THE SPRINKLER SYSTEM FROM i
OPERATING IN THE EVENT OF A FIRE.
The following outlines:
A.
The nature of the problem, B.
How to identify whether your system is a f fected, I
C.
Required course of action.
A.
THE NATURE OF THE PROBLEM We have discovered several 6" valves that failed to trip properly even a fter being serviced within the last six to twelve months.
The valves stuck inside where the latch touches the valve clapper.
We believe that the following factors contributed to the problem.
1.
Relatively high water pressure, (over 100 psi),
2.
Corrosive atmosphere, 3.
Inadequate trip test procedures.
Please note that we may have previously notified you late last year or early this year about this valve.
At that time we recommended a maintenance procedure which has since proven inadequate.
I f your system is of the serial numbers re ferenced below, follow this new procedure.
The corrective action provided by this letter is regarded as a TDiPORARY SOLUTION, but one which should be implemented IMMEDIATELY.
We are preparing a final solution and will notify you when it is available.
It is our current intent to have this final solution available by April 1986.
Although the problem encountered has only been found in 6" Model C valves, we are applying this corrective action to both the 2-1/2" and 6" sizes.
The valves involved in the immediate corrective action recommended by this letter are those manu factured since 1973.

The valves are also identified as " Deluge", "Suprotex",
" Pre-Action", "Suprotex-Deluge", and "Suprotex/ Pre-Action".
In Foam-Water deluge systems, both the water deluge valve and the foam deluge valve may be Model C deluge valves.
The Model C deluge valve has also been installed by Grinnell under the name "Multitrol".
Serial numbers a f fected are:
2-1/2" Model C Deluge Valve :
S/N S4,026 through S10,250 (Excluding SN slo 244, slo 245, and S10246) 6" Model C Deluge Valve:
S/N S6,024 through S12,350 Each Model C valve is identified by a serial number stamped into the front edge of the upper flange and by the lettering "Model C" cast in raised letters on the back of the valve.
C.
REQUIRED COURSE OF ACTION Your present inspection procedure may nct detect a potential mal function; there fore, we strongly recommend that you have a competent technician follow the procedure given below.
At the earliest possible opportunity, the following procedure should be performed on the 2-1/2" and 6" valves in the serial number ranges given above.
A molybdenum disulfide lubricant, 813MS, is required by this procedure.
It can be obtained at no charge by calling the Quality Assurance Manager, " Automatic" Sprinkler Corporation at (216) 526-9900 or 1-800-ASCOA US or your local " Automatic" Sprinkler Office (see attached phone list).
You may also obtain this lubricant by sending a telex request (telex no. 822054) giving the name and address of the location and the name of the person to whom the lubricant is to be sent.
Please provide the serial nut..bers of the valves at your facilities a ffected by this letter.
When each valve is serviced in accordance with the procedures given below, please observe appropriate precautions with respect to any electrical devices connected to the system.
Make sure that the valve under test will not trip other valves.

20555 Attention: Director, Office of Inspection and Enforcement RE: Title 10, Code of Federal Regulations, Part 21, Reporting of Defects and Noncompliances
Dear Sir or Madam:
Recently we have received inquiries from ERC Region I and II about our Model "C" Deluge Valve notification program.
" Automatic" Sprinkler Corporation manufactures and sells a deluge valve for fire protection systems in sizes 2-1/2" and 6" that we call our Model "C" Deluge Valve. This valve is a commercial grade item that is used in some fire protection systems at some nuclear power plants.
We have become aware of a potential problem which may affect the operation of the valve. We would like to point out that we do not believe that this problem is a defect, a deviation, or a noncompliance.
It is a condition that occurs af ter the valves are installed for a period of time.
Regardless, we would like to advise you of our situation and to address to you a response to NRC Region I and II's inquiries.
The valve is listed by Underwriter's Laboratory and approved by Factory Mutual Research Corporation, both independent approval organizations. Each valve is j
tested for operation at both 200 psi and 50 to 75 psi water pressure for i
release of the' clapper and latch prior to shipment.
Every valve functions properly when it ships from our plant.
Following is a chronology of events:
October 1983: We became aware of a fire that occurred at Grand Gulf, Unit 1 Emergency Diesel Generator.
NRC IE Information Notice No. 84-16, dated March 2, 1984 describes this (copy enclosed).
November 1983 thru June 1984: We investigated the incident at Grand Gulf and deduced that the operational failure was peculiar to that facility.
Refer to a letter dated June 4, 1984 to NRC (copy enclosed).

U.S. Nucicar R:gulctory Commissaien Page 2 April 7,1986 November - December 1984: Upon further investigation of the situation, we decided to issue a notification letter to all users of our Model
'C' valve. Enclosed please find a copy of our December 1,1984 notification letter. We included in our mailing campaign all utilities which have a license to operate or construct a nuclear power plant. We advised your office in a letter dated November 19,1984 (copy enclosed) that we would be starting a mailing campaign and a list of the utilities we would notify.
December 1985: As a result of our continued evaluations, it was decided to issue another notification letter (copy attached) that supersedes our December 1984 letter. We advised a temporary solution to the situation and used the same mailing list used in 1984. A copy of our December 12, 1985 notification letter was sent to your office, attention Mary Wegner, via certified mail on January 16, 1986. We have a return receipt dated January 21, 1986 signed by N.W. Natovich.
We have stopped all shipments of our Model
'C" valve.
At present, we intend to change the material of the latch and latch arm.
Once we have finalized this program, we will instigate another mailing campaign.
We will keep you advised of any further developments.
Sincerely, c
