Air pressure regulator R40

for inert gasesspringmulti-stage

Description Highly sensitive, two-step precision pressure regulator working in the flapper-nozzle principle. Solid construction for low-maintenance operation with compressed air or non-corrosive gases. Booster version: In option A version the regulator can also be controlled by pilot pressure up to 7 bar in addition to range spring control. Thereby the regulator becomes a volume booster with double loop, parallel zero point shift Supply pressure: minimum: 0.3 bar above outlet pressure maximum: see chart Air consumption: Constant bleed only when flow is circulating. The greater the difference between supply and outlet pressure the greater is the air consumption, e.g. 9 bar inlet and 7 bar outlet resulting in 3 l/min air consumption. Exhaust: 50 l/min at 1.7 bar outlet pressure and 20 mbar overpressure to outlet pressure Pressure stability: 10 mbar pressure drop when changing flow rate from "0" to "max". Setting accuracy: < 0.03 % outlet pressure. Ten adjusting knob turns for the setting of the whole adjustment range. Gauge port: 1⁄4˝ NPT on both sides, screw plugs supplied Mounting position : any Temperature range: Operating pressure = -4 °C to 80 °C / 25 °F to 176 °F Storage temperature= -20 °C to 100 °C / -4 °F to 212 °F Temperature sensitivity: 1 % pressure deviation at temperature change of 30 °C Material fluid contact: brass, stainless steel, neoprene, aluminium and zinc
