CK

The CK range

CK actuators from Rotork are suitable for all valves in non-hazardous locations. These watertight (IP68 8 m for 96 hours, with double-sealing as standard) actuators are especially suited for applications in the water and power markets.

The CK product range includes standard multi-turn actuators, the CKQ part-turn option, Atronik option for intermediate modest and robust control, and intelligent Centronik equipped actuators. The entire range has a modular design that provides flexibility and high degrees of choice and configurability, enabling a fast order turnaround and quick delivery.

CK actuators are suitable for high temperature and strong vibration environments using separately mounted controls. Continuous mechanical valve position indication is always available, even without power.
