Instruction Manual A41 Valve November 2012 D500211X012 CAUTION The valve configuration and construction materials were selected to meet particular pressure, temperature, pressure drop, and controlled fluid conditions specified in the customer's order.
Instruction Manual D500211X012 A41 Valve November 2012 b. Phoenix III Seal: This seal is bidirectional. For best performance, high pressure at the closed position should be applied to the back (waterway side) of the disc. c. NPS 2 Seal: The preferred direction of installation is with high pressure at the front (retaining ring side) of the disc. Reverse shutoff is permissible at lower pressure (see specifications table).
A41 Valve Instruction Manual November 2012 D500211X012 D Flange Studs: Install two or more line flange studs into the line flanges to help hold the valve in position while centering the valve. Carefully center the valve on the flanges to ensure disc clearance. D Select and install two pipeline gaskets. D Flange Cap Screws: If line flange cap screws are used, be certain the cap screw threads engage the tapped holes to a depth equal to the flange cap screw diameter. 4.

A41 Valve Instruction Manual November 2012 D500211X012 CAUTION It is possible to damage the valve if the actuator travel stops are not properly adjusted before stroking the valve. WARNING Avoid personal injury or property damage from sudden release of process pressure or bursting of parts. Before performing any maintenance operations: D Do not remove the actuator from the valve while the valve is still pressurized.

Optional Shaft-to-Valve Body Bonding Strap Assembly VALVE BODY 37A6528-A A3143-2 VIEW A-A ACTUATOR A A Stopping Leakage For PTFE-filled or graphite standard packing arrangements covered in this manual, often leakage from the packing can be stopped by tightening the packing flange nuts just enough to stop the leak. Use caution when tightening the nuts, overtightened nuts can damage packing box parts.
A41 Valve November 2012 Instruction Manual D500211X012 CAUTION Damage to the disc (key 3) sealing surfaces may occur if the disc is not closed when the valve is being removed from the pipeline. For fail open actuators, it may be necessary to apply loading pressure to the actuator to retain the disc in the closed position while removing the valve from the pipeline. 2. Be sure the disc is in the closed position before attempting to remove the valve from the pipeline or flanges.
Instruction Manual D500211X012 A41 Valve November 2012 Clean all accessible metal parts and surfaces to remove particles that would prevent the packing from sealing. Assembly Inspect the shaft. If it is damaged, it cannot make a good seal with the packing and it must be replaced. If the leakage comes from the outside diameter of the packing, it is possible that the leakage is caused by nicks or scratches around the packing box wall.

A41 Valve November 2012 Instruction Manual D500211X012 1. Removing the retainer ring (key 2): For valves with press-fit retainer rings: D Place the valve on blocks with the seal retainer facing down. (Note: Position blocks so they do not restrict the retainer ring removal.) D Rotate the disc to the open position as shown in figure 7. D On the seal ring side of the retainer ring, locate one of the knock-out points machined on the retainer ring.
Instruction Manual D500211X012 A41 Valve November 2012 WARNING Do not lubricate parts when used in oxygen service, or where the lubrication is incompatible with the process media. Any use of lubricant can lead to the sudden explosion of media due to the oil/oxygen mixture, causing personal injury or property damage. CAUTION Do not rotate the disc past 90 degrees in the open direction. Rotating the disc past 90 degrees can damage the seal ring or other component parts.

Instruction Manual D500211X012 A41 Valve November 2012 c. Lay the retainer ring on the valve body. d. Use a press or a soft-faced hammer to press the retainer ring into its groove in the valve body. CAUTION It takes a considerable amount of force with a hammer to drive the retainer ring into place. Be sure not to damage retainer ring surfaces when installing the ring. e. The retainer ring is properly seated when the face of the retainer ring is flush with the face of the valve body. f.
A41 Valve Instruction Manual November 2012 D500211X012 1. Isolate the control valve from line pressure, and relieve pressure from the valve body. Shut off and disconnect all lines from the power actuator. WARNING The edges of a rotating disc have a shearing effect that may result in personal injury. To help prevent such injury, stay clear of the disc edges when rotating the disc (key 3).
Instruction Manual D500211X012 A41 Valve November 2012 Disassembly 1. If necessary, loosen the packing flange nuts (key 101). This allows the drive shaft (key 8) to turn without the friction caused by the packing. 2. Remove the actuator, using the steps provided in the packing maintenance procedures above, and remove the seal ring using the steps provided in the seal ring maintenance procedures above. 3. Place the valve on a flat working surface with the seal ring slot facing down. 4.

A41 Valve November 2012 Instruction Manual D500211X012 Installing the Hollow Pin and Taper Pin 4. Place the valve body on a flat working surface with the slot for the seal ring facing up. Block the valve body high enough to allow the disc to be rotated into the open position as shown in figure 11. Note Make sure that the taper pins and hollow pins are free of particulate matter before continuing. 5. Rotate the disc to the open position. Locate the disc position mark on the end of the drive shaft.
Instruction Manual A41 Valve D500211X012 November 2012 5. Unscrew and remove the packing flange nuts (key 12), packing followers (keys 15 and 16), and packing flanges (keys 9 and 10) if used, from both sides of the valve. Table 6.
