9500 Valve

Instruction Manual

Form 2433

November 2007

1.Refer to the appropriate actuator instruction manual for assistance in disconnecting and removing the actuator lever. Avoid disturbing the actuator turnbuckle adjustment, if possible.

2.If the valve disc is a Fishtail disc, rotate the disc

180degrees from the original position.

3.Position the disc in its fully closed position. To ensure that disc is fully closed, measure equal distances between valve face and top and bottom of the disc as shown in figure 2 or check to be sure that the flat spot or index mark on the valve shaft is in top-dead-center or bottom-dead-center in relation to the valve.

WARNING

To avoid personal injury, keep hands away from the actuator rod in the following procedure.

4.Note the position of the valve shaft index mark. Index mark alignments for reversed action are not shown in figure 6. To determine proper index mark alignment, proceed as follows:

a.Stroke the actuator to the valve-closed end of travel and retain that position while performing the next step.

b.Keeping hands away from the actuator rod, hold the actuator lever up to the valve shaft so that the lever end is in line with the actuator rod end bearing. The lever index mark that is most nearly in line with the valve shaft index mark is the index mark that must be used during reassembly. If changing to push-down-to-close action with 60-degree operation, the lever index mark will be offset 1 spline tooth from the valve shaft index mark for 12.7 through 19.1 mm (1/2 through 3/4-inch) valve shafts and 2 spline teeth from the valve shaft index mark for 25.4 and 31.8

mm(1 and 1-1/4 inch) valve shafts. This offset must be maintained during reassembly.

5.Record the alignment determined in step 4, remove the actuator lever, and shut off operating pressure to actuator.

6.Reassemble the lever to the actuator and adjust the actuator travel, if necessary, referring to the steps in the appropriate actuator instruction manual. Be sure to use the index mark alignment determined above rather than those shown in figure 6.

Parts Ordering

A serial number is assigned to each valve body and stamped on the nameplate. Always refer to the serial number when corresponding with your Emerson Process Management sales office regarding spare parts or technical information. When ordering replacement parts, also specify the complete 11-character part number from the parts list information.

WARNING

Use only genuine Fisher replacement parts. Components that are not supplied by Emerson Process Management should not, under any circumstances, be used in any Fisher valve, because they will void your warranty, might adversely affect the performance of the valve, and could give rise to personal injury and property damage.
