    Instruction Manual A31D Valve D500248X012 April 2014 Refer to table 2 for the quantity and size of line bolting required to install the valve in the pipeline. CAUTION To avoid damage to the valve disk during installation, the valve must be in the fully closed position. If the A31D valve is equipped with a fail-open actuator, remove the actuator before installing the valve/actuator assembly or cycle the valve into the fully closed position.

Optional Shaft-to-Valve Body Bonding Strap Assembly ACTUATOR VALVE BODY 37A6528-A A3143-2 VIEW A-A CAUTION For non-ENVIRO-SEAL packing: Tighten the packing follower nuts only enough to prevent shaft leakage. Excessive tightening will accelerate wear of the packing and could produce higher friction loads on the valve stem. 2.

  • Page 10: Maintenance

    Instruction Manual A31D Valve D500248X012 April 2014 Note Standard PTFE packing is composed of a partially conductive carbon-filled PTFE female adaptor with PTFE V-ring packing. Standard graphite packing is composed of all conductive graphite ribbon packing. Alternate shaft-to-valve body bonding is available for hazardous service areas where the standard packing is not sufficient to electrically bond the shaft to the valve (see the following step).

  • Page 11: Packing Maintenance

    Instruction Manual A31D Valve D500248X012 April 2014 Packing Maintenance The A31D valve is designed so the packing can be replaced without removing the valve from the process pipeline. CAUTION For non-ENVIRO-SEAL packing: Tighten the packing follower nuts only enough to prevent shaft leakage. Excessive tightening will accelerate wear of the packing and could produce higher friction loads on the valve stem.

  • Page 12: Seal Maintenance

    Instruction Manual A31D Valve D500248X012 April 2014 CAUTION Damage to the valve disk can occur if the disk is not closed when the valve is being removed from the pipeline. If necessary, stroke the actuator to place the disk in the closed position while removing the valve from the pipeline. 3.

As the nut is tightened, the nut will drive the spacer against the disk. The increasing force will draw the pin from the disk.
  • Page 20 Instruction Manual A31D Valve D500248X012 April 2014 CAUTION To avoid damage to the taper key, tangential pins, valve disk, or shaft(s) resulting from the application of excessive force, use appropriate care when driving the key or pins into the disk hub and shaft(s). Use the right tool. Do not use excessive force.
  • Page 21 Instruction Manual A31D Valve D500248X012 April 2014 Key numbers in this procedure are shown in figure 9, 10, or 11 unless otherwise indicated. 1.

    Instruction Manual A31D Valve D500248X012 April 2014 7. Place the flat side of the disk on a flat surface and insert wooden blocks to raise the disk approximately 50.8 mm (2 inches) from the worktable surface. Then, suspend the valve body over the disk so the seal/T-slot area is facing up. Align the shaft bores through the disk with the drive shaft and follower shaft bores.

  • Page 23: Parts Ordering

    Typical parts are shown in figure 9, 10, or 11.
