Tuf-Air Actuators

Tuf-Air T-series actuators feature bi-directional pinion travel stops. Side located stops allow a full 5in of valve travel adjustment that ensure a guaranteed range of adjustment between 80º and 100º of actuator travel. These travel stops are designed to absorb the maximum rated torque of the actuator and the maximum impact loads associated with recommended stroke speed.

As part of the standard assembly, adjustment of the clockwise and anti-clockwise rotation limits are accomplished by turning the respective left and right stop adjustment screws to reduce or increase output rotation.
