Then, position the valve disc from 0 to 0.76 mm (0 to 0.030 inch) away from the internal stop in the valve body. 2. Now, travel the actuator to the maximum position. Keep the actuator in the maximum travel position. Return the actuator to the valve, taking care not to disturb the position of the valve disc. 3.

View of Stud Bolts D In certain services (process fluids with high concentrations of entrained solids, abrasive slurries, or polymerizing media), valve performance will be enhanced by installing the valve with the shaft horizontal to the pipeline. D Valves supplied for unidirectional shutoff should be installed with the high pressure at the back (waterway side) of the disc.

Repeat this procedure several times increasing the torque value each time by a fourth of the final desired torque. When the final torque value has been applied, tighten each flange bolt again to allow for gasket compression. For Single Flange Valves: 1. Position the valve between the flanges.

D Always wear protective gloves, clothing and eyewear when performing any maintenance operations to avoid personal injury. D The valve packing area may contain process fluids that are pressurized, even when the valve has been removed from the pipeline. Process fluids may spray out under pressure when removing the packing hardware or packing rings.

Instruction Manual Form 5338 February 2007 A11 Valve CAUTION In the following step, use the appropriate tool to avoid damage to the seal or T-slot area of the valve. 4. Different valve types have different seal designs and components. To see the appropriate seal, refer to figure 5. Insert the appropriate tool under the top edge of seal and gently pry the seal out. Take care not to damage the seal or T-slot area of the valve body.

Use the seal tool to apply pressure to the backup ring and carefully tuck the backup ring down into the T-slot between the valve body and the seal ring. Note: On larger valves, it may be more efficient to have someone hold down the seal ring while the backup ring is pushed into the T-slot. 3.

Instruction Manual Form 5338 February 2007 A11 Valve CAUTION If a vise or other clamps are being used, be sure damage is not done to the flange gasket sealing area of the valve body. 7. Manually rotate the valve shaft to turn the disc clockwise to meet the seal. 8. Tap the disc with a rubber mallet to drive it against the internal travel stop. When the disc makes contact with the stop, manually rotate the disc counter-clockwise back out of the seal to a 90_ open position. Repeat steps 7 and 8 three times.

Packing Configurations Note The disc must be removed from the waterway side of the valve body, which is the side opposite the T-slot area. Support the valve and disc so the disc can be easily removed from the valve when the shaft is removed. 3. Use a pin extractor to remove the disc pins (key 6). Select the proper pin extractor tip with screws of proper thread size to match the thread size in the disc pins. 4.
