Maxpro Technologies now offers its newly designed air operated valve actuators. These actuators are a piston type design, and are mounted on a standard valve body to provide remote control capabilities in process applications. Two styles of air actuators, piston style valve and yoke style design, are available, and selection is based on the valve size, system pressure and air pressure available. The yoke style design offers separation from process fluids and actuator air pressure. This design also indicated stem position and allows for stem replacement. The actuators are available in two different sizes to cover varying plant air supplies. They are made of anodized aluminum, which provides good corrosion resistance, and are available in normally open or normally closed configurations.
