Rotork CKQ part-turn valve actuator

Rotork has announced that its CK range of modular electric valve actuators has been extended to include a part-turn variant, known as the CKQ. The entire range has a modular design that provides flexibility and high degrees of configurability, enabling a fast order turnaround and quick delivery. CK actuators provide flow control in non-hazardous locations and are especially suited to diverse applications in the water and power markets.

The CKQ part-turn variant is suitable for harsh and demanding environments and has an operational temperature range of -30 to +70°C. The IP68 enclosure protection is maintained even when the actuator terminal housing is removed by using a double-sealing system around both parts of the plug and socket connection. This contributes to its suitability for use within the water market. Continuous mechanical valve position indication is provided (even without power) and the CKQ provides up to 60 starts/h at a rate up to 1 start every 6 s. All options within the CK range provide oil bath lubrication for extended life and mounting in any orientation, and motor-independent handwheel operation is available.

The modular structure of actuators in the CK range means a wide variety of options and features are available. This includes the CK Standard actuator, the Centronik (for intelligent, integral control) and the Atronik option for intermediate modest control.
