Vane-Type Rotary Pneumatic Actuator / Limit Switch Box / Positioner
Kinetrol was established as a firm of control engineers in 1958. Initially, the company’s activities were based on its damping expertise which led to the development of Kinetrol’s rotary viscous dashpots for smooth motion control.
Kinetrol later invented and patented its vane-type rotary pneumatic actuator, recognising the emerging need for quarter-turn valve and mechanism actuation.
Product
Single Acting Spring Return
Pneumatic Actuators
Featuring Kinetrol’s highly reliable, low stress range, clock type spring units, our spring return single acting rotary actuators offer the safest fail-safe operation, ideal for your critical applications. Having the lowest torque loss, typically only 20% through 90°, it enables the selection of smaller sized actuators when compared with typical rack & pinion actuators.
Double Acting Pneumatic Actuators
Kinetrol’s double-acting vane-type rotary actuator models are renowned for their reliability & efficiency, with up to 4 million operations guaranteed giving long maintenance-free life. Our actuators are also highly durable, with millions of units in operation worldwide. The unique single moving vane design delivers greater accuracy for modulation.

Stainless Steel Actuator
Let Kinetrol help you with your requirement for Stainless Steel actuators. Kinetrol’s stainless steel units use our proven quarter turn vane design in a CF3M casing. Currently available: Model 07.
Materials of Construction
Casing: CF3M / 316L Stainless steel
Limit Switch Box
Standard / Explosion ProofKinetrol’s VLS limit switch box can be direct mounted onto our rotary vane actuators or fitted to any other make of rotary actuator using the optional discrete VDI/VDE interface. A wide range of signalling options and terminal arrangements are available for both general use and, hazardous area use.
Positioner
Electropneumatic / Pneumatic
Kinetrol’s range of electropneumatic positioners provide fast, smooth and accurate control for quarter turn actuators.
The EL positioner uses a unique low power proportional servo valve to control the position of a quarter-turn actuator.
Fast-Line
Fast Acting Actuator Booster BlocksSpecially developed booster valve blocks which deliver super fast operating times for larger actuators with exceptional reliability (over 1 million actuator cycles) and durability. With redundancy built in, they make a unique option to consider for ESD valve packages.
Dashpot Products
Our rotary hydraulic dampers known as dashpots are for continuous or part turn applications.
Kinetrol rotary dashpots are precision fluid damping devices which give a smooth resistance
to shaft rotation which increases with angular velocity.
Safe-Line Products
Our extensive range of damped, manual and fire fail-safe units
• Manual Fail-Safe Spring Handles
• D-Line Damped Manual Fail-Safe
• Fire Fail-Safe Springs
Geared Manual Overrides
Available for Models 05 to 21, Kinetrol’s declutchable geared manual override units are rated for the same torques as the actuators. Fitted between the load and actuator, the units are available as either right or left hand.
