87/88 Reciprocating Valve Mounting

This section describes the procedure for mounting the FVP on reciprocating control
valves and uses the GE Masoneilan 87/88 Multi-Spring actuator as an example. See
Figure 30 on page 47 for an example of an FVP on a reciprocating valve.
Tools Required
❑
7/16" Combination Wrench (2 required)
❑
3/8" Combination Wrench
❑
1/2" Combination Wrench
❑
4 mm Hex Wrench
❑
3/16" Hex Wrench
1. Mount the FVP mounting bracket to the actuator using two (2) 5/16 - 18 UNC cap
screws. Unless otherwise specified mount the FVP with the actuator is in the normal
upright position. The slotted opening of the mounting bracket is on the left when
facing the actuator.
2. Clamp the FVP lever (Figure 29) to the FVP shaft.
The flat side on the FVP shaft must always face the pneumatic block with the lever
orientated towards the cover.
When using a standard lever, the orientation of the lever to the FVP is set by clamping
screw location relative to flat on shaft. Leave approximately 1/16" space between the
FVP housing and back of lever.
3. Attach the right hand threaded rod end to the FVP lever using a 1/4 - 20 x 1?h cap
screw. The lever hole position to be used is dependent upon the specific valve stroke.
Refer to Table 2 for lever hole positions.
