Rotork K-Tork Range - Pneumatic Valve Actuator

Brand: Rotork PLC
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.
Features
  • Available in double-acting or spring-return configurations
  • Torque outputs up to 18,300 Nm (155,000 lbf.in)
  • Simple, one moving part
  • Capable of millions of operations at fast cycle times
  • Easy to convert from double-acting to spring-return
  • Precise modulating for quarter-turn control valves with accuracy of 0.25% or better
  • Low friction, dual opposed lip seals provide extremely long life
  • Totally enclosed, non ventilated spring housing
  • Conforms to VDI/VDE 3845 control accessory mounting standards
  • Fast operation with large ports and no air restrictions
  • Complies with ANSI /AWWA C540-02 and C541-08
  • Standard 80 to 100° rotation, adjustable
  • Certified to IP66M / IP67M and meets NEMA 4/4X
  • CE marked and certified in accordance with ATEX 2014/34/EU
  • Standard temperature rating -20° to +70° C (-0° to +160° F)
  • Working pressure 7 bar (100 psi) or 10 bar (150 psi) rating
  • Standard ISO 5211 drive on all spring return models
  • Options:
    • High temperature (+149° C, +300° F) and low temperature (-40° C, -40° F) options
    • De-clutch gear manual override
    • ‘RANGER CG’ Corrosion Guard finish
    • Integral air fail-safe reservoir
    • Full range of open/close, modulating or Bus Network controls
    • Retrofit and factory fit linkage kits, valve automation services
    • Male shaft adapter for spring-return models
