Why K-TORK?
K-TORK Actuators & Controls have earned an excellent reputation in the industry, because our customers know that we deliver what we promise.

A TRUE Rotary Actuator
The K-TORK Advantage
Reliability and Reduced Maintenance
High Accurate Modulating Control

K-TORK high performance actuators provide simple, accurate, and reliable valve automation to many industries. Whether you are replacing an actuator or considering a new installation, the same factors apply.K-TORK Actuators and Controls simply offers more value.

K-TORK is a TRUE ROTARY ACTUATOR
Traditional piston-style actuators convert LINEAR MOTION to ROTARY MOTION by means of cranks, gears, or levers. This "conversion" creates slop, hysteresis, side-load, torque loss,high friction, and/or dangerous pinch points. The strength of K-TORK is its simplicity (only one moving part), NO HYSTERESIS and NO O-RING SEAL design.
