Product description

Pneumatic Actuators for Quarter-Turn Valves and Dampers
Torques to 1,600,000 in. lbs.
Available in Double Acting and Spring Return
The Triac line of heavy duty scotch yoke actuators offer 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 gives high cycle life and smooth stroke while minimizing wear points. As with all Triac actuators, our THD series comes with a complete line of accessories, including jackscrew, hydraulic overrides, limit switches, solenoids and positioners. A-T Controls also offers complete mounting hardware to integrate our actuator with any quarter-turn valve, damper or louver.Contact us for application assistance.
