Design and operation The gas pressure regulator is designed to keep the outlet pressure constant within given limits, independent of disturbing influences like inlet pressure and flow rate changes. This regulating operation is controlled by the pilot which feeds loading pressure to the main diaphragm to change its opening position for a regulation of the gas flow within the main valve. The amplifying valve in the double diaphragm system of the control unit is closed at zero flow. Due to the function of the throttling valve upstream of the pilot ensuring pressure compensation, inlet pressure will prevail in the loading pressure chamber above the main diaphragm. The closing spring gives the force to ensure tight shut-off on zero flow. The valve in the control unit of the pilot reduces the loading pressure to open the regulator (when the two-stage pilot HON 60a is used, an initial decrease of the load limiting pressure is followed by a reduction of the loading pressure within the loading pressure chamber). The inlet pressure prevailling at the lower side of the main diaphragm moves the diaphragm upwards to set free as much of the slotted valve part as is necessary for outlet pressure control. start-up valve load limiting pressure pilot HON 60 measuring impulse line inlet pressure throttling valve load limiting stage control stage filter HON 90 inlet pressure line amplifying valve vent line bleed line loading pressure line closing spring loading pressure chamber main control diaphragm expansion piece main valve body inlet pressure outlet pressure inlet pressure outlet pressure load limiting pressure loading pressure atmosphere main valve
