Recentnenc3ed course of action.
A.
THE STURE OF THE PROM N Within the last year we have had three reprted instan s, involhing seven valves, in which 6" ledel C deluge valves failed to trip when full water pressure was applied to the valve.
It a;5 ears that the impact of the release weight (item 22 on the attached drawing G-14) was not sufficient to disengage the latch, (iten 12) frcin the clapper (iten 6) un&r rtain time, pressure and water conditions.
All three reprted failures occurred in the 6" Model C deluge valve size, operating tnder relatively high pressure, (over 100 psi) and installed for cver 6 years.
It is felt that the roughness of the two mating surfaces, the claEper nose and latch, may change enough to prevent opening bemuse of increased starting friction.
Bcwever, we have been unable to as rtain precisely what canditions cause the change in surface roughness in the isolated cases reported to chte.
We cb knw that all valves have been factory tested before shipnent.
'Ihis test is at high (200 psi) and medium (50-75 psi) gessure.
We further caution you that this conditico may not be evided.
Superficial inspections may not satisfactorily duplicate actual fire conditions.
You may think your valve would work when in f act it would not. Your system's acttal pressure may be greater (over 100 psi) when a fire punp is operating than when in the static condition.
Sin your prese2 inspection gocedure may not detect a ptential re1 function, we strongly recccmend that you have a ccrapetent mechanic follow the below medicned procedure. Where we have encountered the goblen, this relatively simple gocedure has restored the valves to goper working order.

SUBJECT:
DELUGE, PRE-ACTION AND FOAM-WATER DELUGE SPRINKLER SYSTEMS:
MODEL C DELUGE VALVES Gentlemen:
We have become aware of a potential problem which may affect tha fire protection sprinkler system in your building or property.
I f the problem exists, IT MAY PREVENT THE 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 fected,
l C.
Required course of action.
A.
THE NATURE OF THE PROBLEM We have discovered several 6" valves that failed to trip properly even after being serviced within the last s ix to twelve monthc.
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 precedure 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 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 j
valves, we are applying this corrective action to both the 2-1/2" 3
and 6" sizes.
The valves involved in the immediate corrective action recommended j
by this letter are those manu factured since 1973.

HOW TO IDENTIFY WHETHER YOUR MODEL C SYSTEM MAY BE AFFECTED Model C deluge valves are installed in Rate-o f-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 Systems.
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 slo 246) 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 Ballow 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 O f fice (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 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.

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 mechanism.
Remove the hand hole cover.
Remove the clapper.
3.
Inspect the clapper and latch mating sur faces.
These surfaces must be smooth.
Refinish 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 replace the hand hole cover.
Slowly open the OS & Y control 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 safely conduct a partial flow test, it is recommended that a partial flow test be performed as follows :
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.
