The innovative Rotork CK range of modular electric valve actuators has been extended to include a new 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 for diverse applications in the water and power markets. This new part-turn variant is especially well suited for harsh and demanding environments and has an operational temperature range of -30 °C to +70 °C (-22 °F to +158 °F). 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 ideal 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 per hour at a rate of up to 1 start every 6 seconds. All options within the CK range provide oil bath lubrication for extended life, mounting in any orientation, and motor-independent handwheel operation 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 sophisticated Centronik (for intelligent, integral control), and the Atronik option for intermediate modest and robust control. The flexibility of these options within the CK range allows customers a variety of choices for all their flow control requirements. The diverse applications that CK actuators serve mean customers have access to many robust flow control options that will perform in all situations, meeting exact user requirements.
