When mounting an actuator on a valve, never drive the actuator electrically,
instead use the handwheel.
1.
When coupling the actuator to the valve a mounting flange (
12
) type EL5972 or type
EL5973 is required.
2.
Remove the actuator retaining nut (
15
) from the valve and place the mounting flange over
the valve bonnet thread.
3.
Refit the actuator retaining nut (
13
) and tighten.
4.
Remove the actuator pillar nuts (
13
). Using the handwheel retract the actuator spindle.
5.
Screw the valve stem lock-nut (
14
) 2 x valve stem diameters onto the valve stem.
6.
Lower the actuator onto the valve so that the pillar shoulders sit squarely against the
mounting flange.
7.
Refit and tighten the pillar nuts (
13
).
3.2.2 AEL56_ actuator connection to valve
Important: Disc springs must be assembled correctly.
There are 2 sets of 3 disc springs, which must be assembled in the correct order. The convex
side of a spring must be assembled to the convex side of the next spring. Conversely, the
concave side of the spring must be assembled to the concave side of the next spring.
Insert the first set of springs (
9,
see Figure 5)
inside the actuator adaptor mounting. Next
push the valve adaptor
(
10
) inside the actuator mounting so that the springs are pushed up to
the top. Push the second set of disc springs (
9
) over the adaptor nut (
11
) into the actuator by
hand. The nut should be screwed in until the adaptor is held firmly inside the actuator, but not
too tight such that the adaptor cannot be rotated.
