With the emergency hand actuator type HNG, automatic valves with double and single-acting actuators can be manually operated at any time.
In the case of failure in the air or electricity supply the actuator can be operated by means of a disengageable worm drive with hand wheel.
A mounting kit between actuator and valve does not belong to the delivery package of the emergency hand actuator and is to be ordered separately.
