Compressed air pressure regulator R03J

for inert gasesdifferentialsingle-stage

Pilot-operated volume booster with positive bias designed to supply outlet pressure equal to signal pressure plus an adjustable preset spring constant. With very high forward and reverse flow characteristics and excellent sensitivity. A typical application is balancing or regulating pressure in tanks. Media: oil-free and 5 µm filtered compressed air or non-corrosive gases Supply pressure: max. 16 bar Ratio: 1:1 Pilot pressure: max. 10 bar, accordingly lower in the case of manual pre-pressure setting, pilot port G1/8 Accuracy: at supply pressure change from 2 bar to 7 bar = < 6 mbar pressure deviation at flow rate change from 0 l/min to 20 l/min = < 20 mbar pressure deviation response sensitivity = < 2 mbar Air consumption: 1.5 l/min at P1= 5 bar, 2 l/min at P1= 7 bar, 4 l/min at P1= 10 bar, < 1% of volume flow Relieving function: relieving Relief capacity: 700 l/min at 6 bar outlet and 0.35 bar overpressure above setpoint Gauge port: G1/4 on both sides of the body, one screw plug supplied Mounting position: any Temperature range: 0 °C to 60 °C / 32 °F to 140 °F, for appropriately conditioned compressed air down to -30 °C / -22 °F Body: zinc die-cast Elastomer: NBR/Buna-N
