Spring-Return Actuator

K-TORK Actuators + Controls introduces spring-return fail-safe pneumatic actuators to complement the range of double-acting actuators.  K-TORKhigh-performance actuators offer 'True Rotary' valve control without a "linear-to-rotary" conversion, eliminating the hysteresis and lost motion that contribute to modulating control accuracy.
