Our lineup of pneumatic actuators consists of diaphragm motors (single action) and piston cylinders (single and double action). Diaphragm motors are the more popular. Piston cylinders are used for high-pressure valves and large-caliber valves requiring significant output and long strokes.
Our positioners include electric/pneumatic positioners and pneumatic/pneumatic positioners. (Please refer to the page for smart valve positioners.)
