Adaptation of actuator stroke to the valve stroke

The factory-set actuator stroke corresponds to the stroke named on the ID-label + 1 mm
(0.04 inch). If an application requires stroke adjustment, proceed as follows (comply with
min./max. stroke; see "Technical Data"):
Important
With a mounting position other than IMV 1, drain the oil until the oil level is below the thrust rod
cover (Fig. 5/13).
1.
Manually drive the thrust rod completely out. The internal limit stop should now be touching
the driving sleeve.
2.
Loosen the screws of the thrust rod cover and remove the cover.
3.
Open the screw plug in the thrust rod cover.
4.
Both Allen clamping screws are accessible through the opening. Loosen the screws.
5.
Use the hand wheel to drive in the thrust rod until the actuator stroke matches the required
valve stroke.
6.
Turn the internal limit stop (slotted ring nut) clockwise until it is touching the drive sleeve.
Finally, turn it back approx. 1 turn.
7.
Tighten both Allen screws to the required torque.

8.
Reattach the cover for the thrust rod.
9.
Screw in the lateral screw plug.
10.
Fill the oil according to mounting position.

1.
Drive the thrust rod completely in and put the actuator onto the valve yoke.
2.
Make sure the valve stem is aligned with the center of the bore and at right angles to the
actuator seat (permissible parallel deviation < 0.1 mm (0.009 inch) with regard to total
stroke).
3.
Fasten the actuator to the yoke with screws of property class 8.8 (tensile strength 800
N/mm
2
(116032 pounds/square inch); yield strength 640 N/mm
2
(93550 pounds/square
inch)).
4.
Use the hand wheel to drive the thrust rod out; link the rod with the valve stem via the
coupling.
5.
Manually retract the thrust rod to check whether or not the external stop of the actuator is on
the housing flange before the valve cone touches the cover.
6.
If required, adjust with the coupling (only possible within certain limits!).
