Abstract
A fail-safe electromagnetic linkage has a support device for a valve head, and an actuator component actuable by an actuator. The support device is coupled to the actuator component while power is supplied to the electromagnet and decoupled from the actuator component while power is not supplied to the electromagnet. The assembly further comprises a return mechanism configured to drive the support device relative to the actuator component if power is not supplied to the electromagnet.
