Fail Safe Return 600Nm 45S IP68 ATEX CSA Explosion Proof Valve Actuator

The DCL-Ex explosion-proof electric actuator range offers an optional fail-safe module for hazardous-area valves requiring a defined response to external power loss.

When external power is unexpectedly disconnected, stored energy powers the motor to move the valve to a preset fully open or fully closed position, or retain its current position. Once external power returns, the actuator
