Rotork CQ range of compact helical valve actuators

The RFS CQ range is a fully concentric balanced design based on a helical mechanism, transforming the linear motion of the piston into a quarter-turn rotation of the valve stem to operate a comprehensive range of valve types.

The actuator is a balanced and self-contained solution which is suitable for both hydraulic and pneumatic applications. The product can be used in harsh environmental conditions where functional integrity and safety is required and where space is limited, and in applications where a conventional scotch yoke actuator cannot fit.

The versatile mechanism allows the use of many cylinders for each mechanism size. The range features different actuator builds for many different applications. The design allows for complete customisation of the torque profile to meet custom requirements.
