THD & 2R Actuation

The TRIAC Heavy Duty Scotch Yoke Actuator product line offers a broad range of torques to 1,600,000 in-lbs. The THD series is designed to operate ball, butterfly, plug valves, dampers or any device that requires a quarter turn movement for on-off or throttling service. Our standard offering is the symmetrical design yoke that delivers maximum torque at both ends of the 90o cycle. The square slide bearing with guide bar provides high cycle life and smooth stroke while minimizing wear points.
