Instruction Manual Control-Disk NPS 14-36 D103545X012 April 2011 If the Control-Disk valve is equipped with a fail‐open actuator, cycle the valve into the fully closed position. Ensure the valve cannot open during installation by using a manual actuator, a constant supply pressure to the pneumatic actuator, or other steps as necessary. Table 3.

Instruction Manual Control-Disk NPS 14-36 April 2011 D103545X012 A Control-Disk valve is normally shipped as part of an assembly with an actuator and other accessories such as a valve positioner. If the valve and actuator have been purchased separately or if the actuator has been removed for maintenance, properly mount the actuator and adjust valve/actuator travel before inserting the valve into the line.

For Wafer‐Style Valves: Properly orient the valve according to the specific application. Place the valve in the line so the flow properly enters the valve as indicated by the flow tag. Then, install the valve and the gaskets between the flanges into the cradle formed by the flange bolts. 4. Install the remaining flange bolts.

Excessive tightening will accelerate wear of the packing and could produce higher friction loads on the valve stem. 1.

For more information, refer to the Packing Maintenance section below. Maintenance Valve parts are subject to normal wear and must be inspected and replaced as necessary. The frequency of inspection and replacement depends upon the severity of service conditions. Key numbers in this procedure are shown in figure 9 unless otherwise indicated.

A damaged shaft could cut the packing and allow leakage. 1. Before loosening any parts on the valve, release the pressure from the pipeline.
PAGE 13
Instruction Manual D103545X012 Control-Disk NPS 14-36 April 2011 CAUTION Be careful when cleaning the packing box. Scratches to the upper shaft (key 3) or inside diameter of the packing bore might cause leakage. 4. Before installing new packing, clean the packing box. 5. Install new packing one ring at a time, using the packing follower as a driver. If using split‐ring packing, stagger the splits in the rings to avoid creating a leak path. 6. Reinstall packing parts.

Instruction Manual Control-Disk NPS 14-36 April 2011 D103545X012 2. Lay the valve flat on a work bench in a secure position with the retaining ring (key 18) and retaining ring screws (key 19) facing up. Properly secure the valve on a suitable worktable so it cannot slip, twist, or fall during maintenance. Remove all retaining ring screws. 3. Remove the retaining ring by placing a socket head cap screw from the retaining ring in each of the two retaining ring jacking screw holes.

Carefully tuck the O‐ring downward into the body T‐slot until the seal ring is completely entrapped in the body T‐slot, and it completely covers the backup O‐ring. 4. Re‐install the retaining ring and the socket head cap screws. Tighten the cap screws just enough to eliminate any movement of the retaining ring. Do not over‐tighten the retaining ring screws.

Control-Disk NPS 14-36 Instruction Manual April 2011 D103545X012 2. With the seal ring inserted all the way around the body T‐slot now lay the O‐ring into the opening between the valve body and the seal ring. Use the seal tool to apply pressure to the O‐ring and carefully tuck the O‐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 you push the O‐ring into the T‐slot. 3.

Instruction Manual Control-Disk NPS 14-36 D103545X012 April 2011 If necessary, use a wheel puller to remove the lever or actuator from the valve shaft. It is okay to tap the wheel puller screw lightly to loosen the lever or actuator, but hitting the screw with excessive force could also damage internal valve parts. Key numbers in this procedure are shown in figure 9 unless otherwise indicated. 1. Remove the valve from the pipeline. Remove the actuator from the valve.

Control-Disk NPS 14-36 Instruction Manual April 2011 D103545X012 6. The gasket retainer (key 20) on the side of the valve opposite the upper shaft must be removed before removing the lower shaft. Remove the hex head bolts (key 23) and lockwashers (key 22) from the gasket retainer and remove the gasket retainer and gasket (key 21) to expose the end of the lower shaft. 7. Before removing the lower shaft (key 4), be sure the valve disk is properly supported. Pull the lower shaft from the valve body.

Instruction Manual Control-Disk NPS 14-36 D103545X012 April 2011 2. Inspect all parts removed from the valve for wear or damage. Replace any worn or damaged parts. Clean the valve body and all parts to be installed with an appropriate solvent or degreaser. Note When installing the bearings, apply lubricant to the outside diameter of the bearing for ease of installation.
PAGE 20
Control-Disk NPS 14-36 April 2011 Instruction Manual D103545X012 CAUTION To avoid damage to the tangential pins, disk pins, valve disk, or shaft(s) resulting from the application of excessive force, use appropriate care when driving the pins into the disk hub and shaft(s). Use the right tool. Do not use excessive force. 12. Install the appropriate tangential pins, and disk pins. Use 2 tangential pins that will go through the upper shaft and 1 disk pin that will go through the lower shaft. 13.
