Large Bore Spring Return Actuator

The large-bore spring-return actuator is a heavy-duty, single-acting, spring-return Scottish yoke pneumatic actuator designed specifically for the automated control of large ball valves, butterfly valves, plug valves, and other 90° rotary valves. Equipped with a 700 mm large-bore cylinder and a reliable spring-return mechanism, this actuator delivers powerful and stable output in high-torque applications while ensuring safe return in the event of air supply or control signal failure.Powered by compressed air and utilizing a Scottish yoke drive mechanism, this actuator opens and closes valves smoothly and reliably. With its robust construction, stable operation, and high adaptability, this actuator is suitable for demanding applications in the oil and gas, chemical, power generation, metallurgy, water treatment, environmental engineering, and large-scale industrial piping systems sectors.
