Damcos™ KC Linear Double-Acting Actuator
You’ll attain superior marine globe valve control with the Damcos KC Double -Acting Actuator.
Designed for intermediate positions and fail set operation, this actuator converts hydraulic pressure into linear motion with thrust delivered proportional to the applied pressure.The KC has no external moving parts and has a built-in device for maintaining pressure at temperature variations. Designed with a built-in crossover valve and a direct visual position indicator for on-site verification
