Set end stop CLOSED

The internal end stops limit the swing angle. They protect the valve in case of limit
switching failure during motor operation and serve the purpose as limitation for
manual operation via handwheel. They may not be used for torque tripping in end
positions during standard operation.
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 grease leakage.
Observe dimension T
The swing angle set in the factory is indicated on the name plate:
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.
