Rotork K-TORK Pneumatic Vane Actuator

K-TORK Actuators and Controls represents the future of valve automation. The vane actuator is a ‘True Rotary’ actuator that does not require the conversion of a linear motion to a rotary motion. The result is a simple, highly accurate and reliable quarter-turn pneumatic actuator that is specified for the most demanding process flow control applications.

Available in double-acting or spring-return configurationsTorque outputs up to 18,300 Nm (155,000 lbf.in)Simple, one moving partCapable of millions of operations at fast cycle timesEasy to convert from double-acting to spring-returnPrecise modulating for quarter-turn control valves with accuracy of 0.25% or betterLow friction, dual opposed lip seals provide extremely long lifeTotally enclosed, non ventilated spring housingConforms to VDI/VDE 3845 control accessory mounting standardsFast operation with large ports and no air restrictionsComplies with ANSI /AWWA C540-02 and C541-08Standard 80 to 100° rotation, adjustableCertified to IP66M / IP67M and meets NEMA 4 /4XCE marked and certified in accordance with ATEX 2014/34/EUStandard temperature rating -20°C to +70°C (-0°F to +160°F)Working pressure 7 bar (100 psi) or 10 bar (150 psi) ratingStandard ISO 5211 drive on all spring return models
