7.1.
Mechanical end stop setting
The mechanical end stops in actuator limit the swing angle. They protect the valve
during motor operation and serve the purpose as travel limitation for manual operation
via crank handle or handwheel.
End stop setting is generally performed by the valve manufacturer prior to installing
the valve into the pipework.
Exposed, rotating parts (discs/balls) at the valve!
Pinching and damage by valve or actuator.
→
End stops should be set by suitably qualified personnel only.
→
Never completely remove the setting screws [2] and [4] to avoid oil leakage.
→
Observe dimension T
min.
Information
●
The swing angle set in the factory (e.g. 90°) as well as the setting range (e.g.
82° to 98°) is indicated in the order-related technical data sheet. The swing
angle can be freely adjusted within the indicated setting range.
●
The setting sequence depends on the valve:
-
Recommendation for butterfly valves: Set end stop CLOSED first.
-
Recommendation for ball valves: Set end stop OPEN first.
