Technical Data Operating temperature Minimum pressure drop Connection size max. 70°C 1 bar 1/ 2", 3/ 4", 1" www. honeywell. com 11 D05F Pressure reducing valve with balanced seat Method of Operation Spring loaded pressure reducing valves operate by means of a force equalising system. 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.
