Process Control Actuators
CVA Range
The CVA range of linear and quarter-turn actuators provide an electrically powered process control operator suitable for most control valve types and sizes. The CVA sets a new standard for process control and valve actuation. Rotork has proven expertise in applying new technologies in the automation of valves to bring enhanced performance and innovative features. This philosophy has now been applied to a new range designed specifically for the exacting demands of process control, specfically continuous modulating control valve applications.

ELB Line Break Detection System
Rotork’s ELB (Electronic Line Break) is a robust self-contained electronic pipeline monitoring system designed for use in the gas & oil industry. It will continuously monitor pipeline pressure dynamics to provide early detection of pipeline breaks and initiate automatic valve actuator movement to an emergency position based upon user-defined parameters. The powerful and versatile system can also collect detailed operational data useful for optimising performance and enhancing pipeline safety.

CQ
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 utilised 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 utilised 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.In our experience, the CQ standard range of sizes is suitable for applications that require a pneumatically powered actuator with torque demand less than 150,000 Nm. However, we also engineer CQ actuators with greater output and/or hydraulic power. Please apply to Rotork for these applications.
