Kinetrol was established as a firm of control engineers in 1958. Initially the company’s activities were based on its damping expertise which lead 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. Since then, the company has added many actuator control modules to meet the growing demand for more precise and sophisticated process control and monitoring.
Kinetrol operates from three sites in Farnham, England, and exports at least 70% of sales to countries all over the world.
Kinetrol has full inspection and test facilities and operates a rigorous quality control programme which includes 100% testing of actuators and dashpots before despatch. The company’s quality system is approved by the British Standards Institute to ISO 9000. Quality is built into Kinetrol’s products by active choice in every part of the company.
King Mechanical Speciality is an Authorized Distributor of Kinetrol Pnuematic Actuators, Spring Return Units, Positioners and Limit Switch Boxes. We stock a variety of sizes and ship orders same day. Our in-house machine shop can fabricate custom couplers and mounting brackets for mounting to any valve.
The rotary design of Kinetrol pneumatic actuators is based upon a single moving part which eliminates additional parts required to convert linear motion to rotary motion. This simple and innovative design provides a highly accurate and extremely reliable actuator performance for operating valves, drives and dampers, and is perfectly suited for the most demanding process control applications.
Kinetrol positioners control airflow to an actuator and moves it to position with fast smooth and precise control from a digital circuit and proportional servo valve.
Calibration is quick and easy via push buttons and LED feedback, making simple field installation. Reversal of rotation sense (clockwise/anti-clockwise) can be carried out without the need for special tools or a change of parts. Kinetrol positioners are weatherproof, compact and have a robust metal housing with an epoxy stove enamel finish.
The Kinetrol Universal Limit Switch is offered in a wide range of signaling options encased in a zinc alloy fully enclosed corrosion resistant case. The Universal Limit Switch is available for direct mounting onto Kinetrol rotary actuators, or discrete mounting via an industry standard VDI/VDE interface onto any make of rotary actuator. Easy to wire and set up with industrial quality robustness. An integral sealed Clear Cone Monitor and red/green Led indicator options also give excellent external visual indication of position.
Kinetrol spring units are available for either clockwise or counter clockwise spring action. Spring units are mounted as standard between the actuator and what it drives. Factory assembled actuator/spring return assemblies are set for balanced torque output when the actuator is operated by air at 80psi. When higher torque is required in one direction, simply change the spring pretension as required.
