The Diaphragm Amplifiers are miniature interface devices which perform the same function as a piloted three-way valve, but at low outlet flow rates. Pneumatic signals of several inches water gauge applied to the input will control the output pressure up to 35 PSI in both digital and analog systems.
Diaphragm Amplifiers are very suitable for providing pneumatic signals to air-piloted valves for powering small cylinders. They are also used at fluidic signal levels for providing isolation and in timing circuits.
