[. . . ] D22 Pressure reducing valve with piston balanced seat Standard pattern for compressed air Product specification sheet Application Pressure reducing valves of this type protect installations against excessive pressure from the supply. [. . . ] The force of a diaphragm operates against the force of an adjustment spring. If the outlet pressure and therefore diaphragm force fall because water is drawn, the then greater force of the spring causes the valve to open. The outlet pressure then increases until the forces between the diaphragm and the spring are equal again. The inlet pressure has no influence in either opening or closing of the valve. Because of this, inlet pressure fluctuation does not influence the outlet pressure, thus providing inlet pressure balancing.
