9500 Valve

Instruction Manual

b.If installing a new shaft, insert the new shaft into the valve body and disc. Measure between the valve body and the splined end of the shaft. Make certain that the distance is correct to engage the actuator coupling lever.

Be certain that the flat spot or index mark on the end of the shaft is positioned as shown in figure 2.

6.Use a drill or center punch to mark the taper pin holes in the shaft. Remove the shaft and disc from the valve body.

7.Taper pins used in Type 9500 valve shaft and disc are American Standard taper pins as shown in table 5. Using the disc as a guide, drill taper pin holes through the shaft using drill size shown in table 5.

8.Use an American Standard taper pin reamer to ream the shaft holes. Be certain the reamer is of sufficient length for the disc hub thickness. Insert the shaft into the disc when reaming so the disc holes can be used as a gauge for reaming. Allow the reamer to just begin reaming the disc holes. This will ensure proper seating of the pins.

9.Install the disc and shaft into the valve body. Be sure the splined end of the shaft is on the actuator side of the valve body, that the direction of taper in the taper pin holes match, and that the flat spot or zero mark is positioned as shown in figure 2.

10.Using a metal sealing compound on the pins for a positive seal, insert the taper pins into the larger end of the taper pin holes. Drive the pins with a hammer to seat the pins.

11.Attach the thrust plates (key 9) with cap screws (key 10). When tightening the cap screws, do so in small increments, alternating from one cap screw to another and from one valve side to the other.

Tighten the cap screws until the thrust plates contact the thrust sleeve assemblies snugly. Then rotate the cap screws enough to move the thrust plates 0.8 mm (1/32 inch) closer to the valve body.

12.Re-attach the actuator according to the steps in the Actuator Mounting section; then install the valve according to the steps in the Installation section.

Actuator Mounting

1.Refer to the appropriate actuator instruction manual to determine the desired actuator mounting style and position. With the valve out of the line, mount the actuator on the valve per instructions in the actuator instruction manual.

2.To determine the fully closed disc position, measure the distances between the valve face and the top and bottom edges of the disc as shown in figure 2. The disc is at the fully closed position when the two measurements are equal. Rotate the disc slightly if necessary to make the measurements equal.

3.Refer to figure 6 and locate the view that depicts the mounting style and position that is being used. In the appropriate view on the right of figure 6, note the positions of the index marks on the end of the valve shaft and actuator lever. For all positions and styles with 90-degree disc rotation, the shaft index mark is to be aligned with the appropriate lever index mark as shown in figure 6. This is also true for push-down-to-open action with 60-degree maximum disc rotation. However, for push-down-to-close action with 60-degree maximum disc rotation, the appropriate lever index mark must be offset one or two spline teeth counterclockwise from the shaft index mark.

Refer to the appropriate actuator instruction manual for instructions covering attaching the lever and adjusting the turnbuckle. For Fishtail discs, be certain that the direction of rotation will be such that the tail of the disc (see figure 2) will rotate into the downstream side of the valve.

Changing Disc Rotation and Action

Disc rotation can be changed from 0-90 degrees or vice versa by changing travel stops in the actuator and, if necessary, changing the position of the lever on the splined valve shaft. Action can be changed from push-down-to-open to push-down-to-close by removing the actuator and remounting it in the alternate mounting style. Refer to the appropriate actuator instruction manual for assistance in disassembly and reassembly to change travel stops and for instructions to change mounting style.

Note

Action for valves using a splined valve shaft can also be changed, without changing mounting style, by repositioning the actuator lever on the valve shaft. For Fishtail discs, it will be necessary to rotate the disc 180 degrees so that the tail of the disc will rotate into the downstream side of the valve.

Use the following procedure.
