9.5 Mounting the actuator to the valve

- Completely retract the actuator thrust rod and put the actuator on the valve yoke.

- Make sure the valve stem is centrically aligned with the bore and at right angles to the actuator seat

(permissible parallel deviation < 0.1 mm referred to total stroke).

- Fasten the actuator to the yoke with screws of property class 8.8 (tensile strength 800 N|mm

strength 640 N/mm

- Use the handhweel to extend the thrust rod, link the rod with the valve stem via the clutch.

- 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 gets in touch with the cover.

- If required, adjust with the clutch (only possible within certain limits!)
