Rotork K-Tork Range of True Rotary Vane Pneumatic Actuators

The Rotork K-TORK range of true rotary vane pneumatic actuators is the solution for the high-cycle, heavy-duty operation of quarter-turn valves and dampers. Unlike standard rack-and-pinion actuators, the K-TORK’s innovative vane design delivers pure rotary motion with zero side-load friction, resulting in exceptional lifespan and ultra-precise modulating control in the harshest industrial environments.
