3 IMO-70EN GENERAL This instruction manual contains important information regarding the installation, maintenance, and troubleshooting of Jamesbury Series " (DN 00) Class 50 Standard Bore, Series 9000 " 6" (DN 50 50) Class 50 and " 4" (DN 50 00) Class 00 Full Bore Valves. Please read the instructions carefully and save them for future reference.. Warning FOR YOUR SAFETY AND PROTECTION, IT IS IMPORTANT THAT THE FOLLOWING PRECAUTIONS BE TAKEN PRIOR TO REMOVING THE VALVE FROM SERVICE OR BEFORE ANY DISASSEMBLY OF THE VALVE:. AT ALL TIMES DURING THIS ENTIRE PROCEDURE, KEEP HANDS OUT OF THE VALVE. A REMOTELY ACTUATED VALVE COULD CLOSE AT ANY TIME AND RESULT IN SERIOUS INJURY.. KNOW WHAT MEDIA IS IN THE LINE. IF THERE IS ANY DOUBT, CHECK WITH THE PROPER AUTHORITY.. WEAR ANY PROTECTIVE CLOTHING OR EQUIPMENT NORMALLY REQUIRED WHEN WORKING WITH THE MEDIA INVOLVED. 4. DEPRESSURIZE THE LINE AND VALVE AS FOLLOWS: A. OPEN THE VALVE AND DRAIN THE LINE. B. CLOSE AND OPEN THE VALVE TO RELIEVE ANY RESIDUAL PRESSURE THAT MAY BE IN THE VALVE PRIOR TO REMOVING THE VALVE FROM SERVICE. LEAVE THE VALVE IN THE OPEN POSITION. C. AFTER REMOVAL AND PRIOR TO ANY DISASSEMBLY, DRAIN ANY REMAINING MEDIA BY PLACING THE VALVE IN THE VERTICAL POSITION AND CAREFULLY OPEN AND CLOSE THE VALVE SEVERAL TIMES. 5. SEAT AND BODY RATINGS THE PRACTICAL AND SAFE USE OF THIS PRODUCT IS DETERMINED BY BOTH THE SEAT AND BODY RATINGS. READ THE NAME TAG AND CHECK BOTH RATINGS. THIS PRODUCT IS AVAILABLE WITH A VARIETY OF SEAT MATERIALS. SOME OF THE SEAT MATERIALS HAVE PRESSURE RATINGS THAT ARE LESS THAN THE BODY RATINGS. ALL OF THE BODY AND SEAT RATINGS ARE DEPENDENT ON VALVE TYPE AND SIZE, SEAT MATE- RIAL, BOLTING MATERIAL, AND TEMPERATURE. DO NOT EXCEED THESE RATINGS. INSTALLATION. Place the valve in the open position.. Flow through a Jamesbury valve can be in either direction. It is recommended, however, that the valve be installed with the insert facing upstream.. IMPORTANT: Tighten the valve between flanges using gaskets and fasteners appropriate for the service and in compliance with applicable piping codes and standards. 4. If there is weepage past the packing upon installation, the valve may have been subjected to wide temperature variations in shipment. Leak-tight performance will be restored by a packing adjustment described in the MAINTENANCE Section. MAINTENANCE General maintenance requires periodic observation to ensure that the valve is functioning well. Routine maintenance consists of tightening the bonnet stud nuts (8) periodically to compensate for stem seal wear. This may be done by tightening the bonnet stud nuts (8) until snug, than tighten an additional /4 turn.. Disassembly NOTE: If complete disassembly becomes necessary, replacement of all seats, packing and bearings is recommended. (Refer to Service Kits, Table.). Follow the steps in the WARNING Section before performing any work on the valve.. Open and close the valve and leave in the closed position.. Remove handle screw (5), handle (), and retaining ring (4) from the top of the stem. 4. Pull off the spring () and indicator stop (). 5. Remove the bonnet stud nuts (8). 6. Remove stop bushings (50) and compression plate (0). 7. Mark the body joint flanges to assure correct body () and body cap () orientation during assembly. Remove body stud nuts (6) and remove body cap (). BE CAREFUL NOT TO SCRATCH THE BALL. 8. Remove the body gasket (65) and the seat (7) from the cap. 9. If the ball () does not swing free from the body, with the ball in the fully closed position, use a piece of wood or some other soft material to gently tap the ball (from the end opposite the body cap). This should loosen the ball so that it can be pivoted free of the stem (5). 0. Remove the second seat (7) from the body ().. Press the stem (5) from the top into the valve body and remove it through the end of the body.. Pry out from the inside the old thrust bearings (70), secondary stem seal (7) and packing (69). BE CARE- FUL NOT TO SCRATCH ANY SEALING SURFACES IN THE BODY.. Remove the spring (6) from the bottom of the stem. 4. If the valve is to be grounded, clean packing bore with crocus cloth or equivalent, to bare-metal surface.

5 IMO-70EN 5. Assembly. Clean all valve components.. Inspect all components for damage before reassembling the valve. Look for damage to the sealing areas, stem, body and body cap, and look for wear in the bearing areas. Replace any damaged parts.. Carefully clean and polish the ball sealing surface. It should be free of all scratches and grooves. 4. If the ball is slightly damaged, it may be possible to smooth the sealing surface with crocus cloth or equivalent. If deep scratches are present, replace the ball or return the valve to the factory for service. 5. Standing the body () carefully on end, install one seat (7). 6. From inside the valve, place a thrust bearing (70), a secondary stem seal (7), and the second thrust bearing into the stem bore. (See Figure for proper orientation.) Place the spring (6) into the bottom of the stem. 7. Insert the stem (5) from inside the body through the bonnet of the valve. 8. Install the packing (69). (If the packing is V-ring type, be certain that they are installed in the orientation shown in Figure.) If the valve is to be grounded, remove one middle V-ring and place graphite grounding washer on top of stack. (See Figure.) 9. Place compression plate (0) over the stem (5) and studs (4). Place stop bushings (50) and nuts (8) on studs (4) and tighten finger tight, then tighten an additional /4 turn. 0. Install the ball () rotating it onto the stem (5) in the closed position. Gently rock the ball to make sure the stem is centered in the ball slot (see Figure, stem-toball location).. Gently place the body gasket (65) into the machined recess of the body ().. Place the remaining seat (7) on top of the ball.. Place the body cap () over body studs () being careful to properly orient body cap and body as originally assembled by matching orientation marks made prior to disassembly. Take care not to damage body gasket (65) or seat (7) during this operation. 4. Lubricate the threads and face of nuts (6) with Never- Seez or equivalent. Install nuts (6) on body studs () and tighten sequentially as shown in the diagram (Figure ), to the recommended torques as shown in the torque chart (Table ). 5. Place the indicator stop () with bottom facing down over the stem so that the longer part is over the body. 6. Place the spring () over the stem (5) with the larger diameter contacting the indicator stop (). 7. Compress the spring () and hold down by putting the retaining ring (4) in the groove in the stem (5). 8. If the valve is to be grounded, test as follows: 4 a. Use an ohmmeter accurate to within +/-0%. b. Check continually between top of stem and body base metal, also check between ball and body base metal. Precaution should be taken to prevent scratching the ball O.D. c. Resistance in either the open, half open or closed position shall not exceed 0 ohms using a source not exceeding volts.

6 6 IMO-70EN 4 SERVICE KITS We recommend that valves be directed to our service centers for maintenance. The service centers are equipped to provide rapid turn around at reasonable cost and offer a new valve warranty with all reconditioned valves. Standard service kits (Table ) include seats, packing, thrust washers and a 6 stainless steel spiral wound body gasket. The body gasket is suitable for valves with carbon steel or stainless steel trim. Consult the factory for replacement parts of valves with trim other than carbon or stainless steel, and for seat materials not listed or for special services. 5 REPAIR KITS/SPARE PARTS For further information on spare parts and service or assistance visit our web-site at TABLE SERVICE KITS* Valve Size Seat Material " (DN 50) " (DN 80) " (DN 80) 4" (DN 00) 4" (DN 00) 6" (DN 50) 8" (DN 00) 950/ PTFE (T) RKN-68-TTT RKN-8-TTT RKN-69-TTT RKN-84-TTT RKN-70-TTT RKN-85-TTT RKN-85-TTT FILLED PTFE (M) RKN-68-MTT RKN-8-MTT RKN-69-MTT RKN-84-MTT RKN-70-MTT RKN-85-MTT RKN-85-MTT PFEP RKN-68-FTT RKN-8-FTT RKN-69-FTT RKN-84-FTT RKN-70-FTT RKN-85-FTT PFA SEATS & SEALS RKN-68-BPT RKN-8-BPT RKN-69-BPT RKN-84-BPT RKN-70-BPT RKN-85-BPT XTREME RKN-68-XTZ RKN-8-XTZ RKN-69-XTZ RKN-84-XTZ RKN-70-XTZ RKN-85-XTZ RKN-85-XTZ * For grounded valves, grounding washers listed below are also needed when ordering.
