Pneumatic Actuated Valves normally include a cylindrical body with ports for the fluid’s entrance and outflow, as well as a valve stem that moves to open and close the flow. The valve stem is linked to a piston or diaphragm that is moved by compressed air. These valves can be divided into three types: single acting, double acting, and spring return pneumatic actuators. Single acting actuators move the valve in one direction and rely on a spring to return it to its original position. Double acting actuators use air pressure to move the valve in both the open and closed positions. Spring return actuators rely on air pressure to move the valve in one direction and a spring to restore it to its original position.
