Single moving part: Simplest and most reliable mechanism for quarter-turn rotary actuation.
Close couple control modules: Fail-safe spring returns, limit switches, positioners and solenoid valves all close couple to the actuators.
No cranks or gearing: No power loss or backlash – allows accurate positioning.
Durable corrosion resistant finish
Long maintenance-free life:
Up to 4 million operations guaranteed.
Compact – space saving – efficient:
 Best torque/size package available, fast operating speeds, best air consumption, proven design.
Hundreds of thousands of units: in trouble free service all over the world.
Choice of male or female output drive square – easy to interface to application
Unique serial number for identification and traceability

Working temperature range:

Standard: -40 C to +80 C

High temperature option: -20°C (-4°F) to +100°C (212°F) using temperature seals for higher temperatures with special equipment – contact us

If consulted Kinetrol may, under certain circumstances/conditions, be prepared to extend its high temperature limits

Low temperature option: -54°C (-65°F) to +60°C (140°F) using temperature seals include option “W” at end of actuator coding.

Maximum recommended working pressure: 100 psi (7 bar)

Maximum overload pressure: 150 psi (10 bar)



Operation or positioning of ball, butterfly, plug and control valves, ventilation dampers and automatic doors. Uses also include movement and positioning of components during manufacture – in fact anything that needs to be turned through 90° or less, automatically or by remote control.
