End stops in part-turn actuator
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.
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 may be set by suitably qualified personnel only.
→
Never completely remove the setting screws [2] and [4] to avoid oil leakage.
→
Observe dimension T
