Rotork CK / CKa / CKc modular multi-turn electric actuator for non-hazardous areas, IP68

Rotork CK is a range of modular multi-turn electric actuators for valves in non-hazardous areas. The actuator is built from stocked modules with short lead time, which is convenient for retrofits where the valve remains and only the actuator is replaced.

IP68 protection (8 m, 96 hours), double sealing as standard. Versions: CK — isolating without integral controls; CKa — with simple integral Atronik starter; CKc — with intelligent Centronik controls and remote mounting option. Modulating versions: CKR, CKRa, CKRc. Mechanical or digital switch mechanism, network protocols.

Direct CK 30–500 sizes provide about 12–500 Nm; series output torque depending on configuration is up to 6,750 Nm. Independent handwheel drive, torque and position limitation. For hazardous areas the IQ3 Pro range is intended.

Key features:

• Modular design and short lead time
