Kinetrol manufactures the most comprehensive range of high performance pneumatic double-acting and spring-return rotary vane actuators in the world. In addition, Kinetrol also manufactures a full range of positioners, limit switch boxes, fail-safe and fire fail-safe spring units, I to P transducers, spring-to-center 90º and 180º actuators, gearboxes and other engineered products from foundry to finished goods in our own ISO 9001-2008 certified factories.

Kinetrol is the inventor of the quarter turn pneumatic vane actuator and manufactures 17 sizes with torque outputs ranging from 8 lb inches to 168,000 lb inches when supplied with 100 psig.

Kinetrol’s exclusive direct-mount modular concept eliminates expensive and unnecessary tubing, fittings, brackets and couplings, which provides virtually hysteresis-free and extremely compact, automated assemblies. Unlike cylinder actuators, Kinetrol’s one piece vane and shaft design move as one resulting in extremely precise modulating and on/off control. Kinetrol actuators use double opposed polyurethane lip seals instead of O-ring seals typically used in quarter turn actuators. Kinetrol’s lip seal design isolates the shaft seal from plant air pressure and also acts as wiper for any foreign material which dramatically extends the service life of these actuators in all applications.

Knock off and copy attempts have come and gone over Kinetrol’s 50 plus year history, but none have come close to Kinetrol’s stellar track record of quality and reliability. Truth is in the performance and Kinetrol actuators have developed the reputation as the most reliable severe service, high cycle actuators the world over since 1958.
