Rotork CQ Range - Compact Helical Actuator

The CQ range provides an innovative fully-concentric and balanced actuator design for quarter-turn valves. 

The design features a helical mechanism that transforms linear piston motion into quarter-turn valve stem rotation. 

CQ actuators provide a much higher torque output for a given footprint than scotch yoke designs typically utilized to operate many quarter-turn valve types. 

It is therefore ideally suited for installation in confined spaces. 

Further, Rotork’s unique helical pin design provides higher efficiency than a helical gear mechanism utilized by other valve actuator manufacturers.

As standard, the CQ torque output profile, like that of a scotch yoke actuator, is engineered to parallel the torque demand profile typically found with popular quarter-turn valve types. 

The CQ design however is unique in that the torque profile can be custom engineered and manufactured to meet specific, non-standard valve torque requirements.
