1.0 INTRODUCTION

1.1 PURPOSE This procedure provides instructions for the disassembly / reassembly of valves. 1.2 SCOPE This procedure is applicable to those valves specifically addressed in the supplements to this procedure. Valves not addressed in the supplements shall be disassembled / reassembled in accordance with 6 Operation Travelers prepared in accordance with CP CPM 6.3. . g 2.0 PROCEDURE 2.1 DISASSEMBLY / REASSEMBLY vs REPLACEMENT PART Y p p Valves which are only disassembled /reass'einbled and which do not O require the additio of s re parts'other than gaskets, stems, seals, packing, a ve seatsWnd handwheels and operators, do not require a travenrr. valves which require the replacement of i l n any other parts than those listed above will require a traveler c { (.) as discussed in paragraph 2.8. Disassembly / reassembly activities shall be performed in acco ance with the supplements to this procedure. Where supplementry. e no t provided, an Operation Traveler shall be prepared in acco nce 7 with CPM 6.3. When necessary, vendor manuals or travelers may be used to supplement this procedure. f Prior to disassembly of a valve, the craft shall prepare an IRN in accordance with CPM 6.10. The IRN shall include the tag number and serial number of the valve. If this information is not avai-i lable on the valve, the craft shall obtain it from the installation %] records in the Permanent Plant Records Vault, and shall permanently mark the information on a steel tag and attach the tag to the valve. A copy of the QA record shall be presented to QC for the verification of identification. 2.2 SEQUENCING i The supplements to this procedure provide the sequencing which should

c.,;..: ;

--7py fj be followed for the subject activities. However, deviation to this .a sequencing is allowed as deemed necessary by the craftsman provided -e. cl' -sood workmanship is used and the manufacturers' recomendations -.g,,j M are followed. i i i r.= -.n ,...-. :::. -.-...= 2:,a. ... 2. 7 : ~ ' - ^ ..':.* L.. -. -~. , m

If the valve is a motor-operated valve, care should be taken to ensure the motor operator is " tagged out" in accordance with l site safety procedures. 2.5 CLEANLINESS Valve disassembly / reassembly shall be performed in an environment I which will not result in contamination which is detrimental to the valve, or its associated parts or piping system. After disassembly the valve body opening shall be covered with a cover which will prevent the entry of contaminants. The cover shall be tape, plywood, plastic caps, or any other suitable material. Mater-O ials should be of a type that will not contaminate the interior of the valve such as deteriorating plywood. Prior to reassembly of the valve the craft shall check the internal surface of the valve to ensure no foreign material is present. All foreign material such as dirt, grinding residue, etc.. shall be removed. I All internal parts, including the valve body and bonnet, and other surfaces which may come in contact with the process J j fluid, shall be cleaned with grade A dimeneralized water prior gr j to reassembly. p ,( 2.6 CARE OF THE VALVE PARTS 9 Valve parts shall be packaged and identified with the valve number to prevent loss or damage and to maintain traceability. The parts n ', ;. ' shall then be securely stored by the Millwrights in the field or the j g:j Millwright Shop. f 2.7 GASKET AND SEAL RING REPLACEMENT ~[y it..M.. New gaskets shall be used to reassemble valves. If a new gasket 7, is not available, the valve may be reassembled using the old gasket, 4 $j and the gasket shall be replaced when the new gasket is received on site. If the old gasket is reused, the bolts should not be torqued. Diaphragms may be reused. O ~ y o eq

Prior to any work Westinghouse must be notified. 2. Remove the main flange nuts in the same sequence used for tightening, see page 2. 1 3. Screw two (2) stainless steel lifting eyes into the threaded holes provided } in the bonnet, raise the bonnet evenly from the body. Remove the gasket. i See page 3, for lifting eyebolt sizes. 4. Inspect the studs for damage. Do not remove the studs. 5. The disc, disc are, collar, lock pin, anti-rotation pin, and bearing blocks. are parts of the disc assembly and will lift out simultaneously. The assembly maybe removed by grasping the disc arm rotating the disc in the opening direction to clear the body, and lifting vertically. For larger siza valves, attach necessary lifting equipment to the disc arm near the disc and using equipment for removal. Again, the disc am assembly must be removed as soon as they clear the body pockets. j Q REASSEMBLY: NOTIFY WESTINGHOUSE PRIOR TO ANY REASSEMBLY i 1. Slide the bearing blocks onto the pivot pin and hold in place while lowering the assembly into place, using necessary lifting equipment. 2. Torque the studs to the value as shown on page 4. Lubricate the stud threads, nut threads, and nut bearing surfaces with 3. Fel-Pro N-5000. 4 Carefully align the bonnet stud holes over the studs and lower the bonnet onto the body. Orient the bonnet so that the lifting eyes are over the '01 run of pipe, a .f S. Nut torquing shall be per values shown on page 5 and sequence on page 2. ,, W" Do not proceed to the next higher torque level until sufficient repetitions have been made to insure that no further nut rotation:is possible. After highest torque has been applied, loosen one nut, completely removing all ,,yg.M [ the torque; then retorque to the design as shown on page 5, proceed to ..i?/g*,/t the adjacent nut and repeat, continue until each nut has been loosened .7'S and retorqued.

Mark the body, yoke and yoke lock ring with prick punch marks so that the parts can be reassembled in their original position. 2. Loosen the gland bolt nuts and tap the gland, which should relieve any pressure which might be trapped in the valve. 3. Remove the bonnet retainer ring cap screws, due'to space limitations, a special tool may have to be used. Make it from a standard allen socket wrench. 4. Open the valve fully so the stem is backseated on the bonnet and impact with the handwheel several times to break the pressure-seal gasket loose from the body. Once the gasket is free, discontinue turning the handwheel. 5. Remove the yoke lock ring studs and nuts. O .. Remove tne yoke iock ring using a smaii pry bar to seperate the haives. 7. To make certain the pressure-seal gasket is free in the body, attach a chain hoist to the handwheel and lift the yoke and bonnet assembly up a maximum of 1/4". Do this with a hoist of at least 1000 lb. capacity, if the stem of the valve is not mounted verticallu, position the hoist slightly away from the handwheel in line with the stem. 8.

No.: AQ-52 Characterization: It is alleged that site maintenance personnel inter-changed parts of an unspecified number of' ASME code stamped valves during a site disassembly operation. It is believed that part traceability to the valves was lost, valved functionality jeopardized and any manufacturers preshipment tests or adjustments if done, as invalidated. Initial Assessment of Significance: The implied significance is that the valves installed may have parts which will fail to operate as intended. ,.j ..)
