De-clutch mechanism for valve operator |
摘要 |
A de-clutch mechanism is actuated, when the power is off, by manual actuation of a de-clutch lever shaft. When thus actuated, the de-clutch mechanism couples a rotatable driven sleeve to a handwheel drive and decouples the sleeve from the power drive. When the power is activated, the de-clutch mechanism automatically disconnects the handwheel drive. A typical application of the de-clutch mechanism is in valve operators.
