Triac THD scotch yoke actuators deliver up to 1,600,000-in.-lb / 180,800 nm torque.
The heavy-duty designs meet demanding liquid and air handling duties to power quarter-turn valves and dampers in oil, gas, chemical, water/wastewater, and pollution control applications.
They are designed to operate ball, butterfly, and plug valves, dampers, or louvers — any device that requires quarter-turn movement for on-off or throttling service.
THD employs a symmetrical-design yoke that delivers maximum torque at both ends of the 90° cycle. They come with six basic body designs, each available in spring-return or double-acting versions and 40 to 100 psig operating air pressures.
Modular actuator design allows mixing power groups and spring cartridges with different center body sizes to suit different air pressures and requirements for fail-clockwise or fail-counterclockwise operation.
A square slide bearing and chrome-plated piston rod, guide bar, and pressure cylinder deliver smooth stroke and extended performance while reducing wear points.
Triac THDs are rated from -20° to +200° F. / -29° to +93° C. with an optional low rating of -40° to +180°F. / -40° to + 82°C. or high 0° to +350° F. / -18° to +177°C. Complete scotch yoke actuators details are yours free.
