Product Description
Pneumatic actuators are used for the mechanical opening and closing of various types of equipment, including dampers, butterfly valves, ball valves, industrial machines, furnaces, burners, and heating devices. These air-operated units utilize differential pressure compared to atmospheric pressure to generate mechanical motion for slow or fast rotation or shifting between positions.
Pneumatic actuators are highly powerful, reliable, and compact units with fast or slow 90° rotation. They are manufactured in both single-acting and double-acting versions. In addition to the standard manufacturing process, actuators can also be produced with ± 5% stroke adjustment, 180° rotation, and three closing positions (closed, open, half-open). Suitable for use with ball valves, butterfly valves, threads, and dampers.
