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 Rotork 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, Rotork also engineers CQ actuators with greater output and/or hydraulic power. Please apply to Rotork for these applications. 

Main features that should be noted:

• Pneumatic actuator in double-acting and spring-return configurations - by compact design
• Fail-close/fail-open
• For on/off
• Torque output up to 150,000 Nm (110,634 lbf.ft.)- higher torques are available on request
• Certified to IP 66M/67M
• Certified to ATEX 2014/34/EU
• Certified in accordance with PED 2014/68/EU
• Certified suitable for use at SIL3 as a single device with IEC 61508
• Ease of Maintenance 
• Environmental Protection
• Balanced Design - minimal stress on valve

• Manual Override
• Closed Loop System 
• Complete Control Systems
• Special Paint
