Compressed air pressure regulator R750

for inert gasesmembranemulti-stage

Description The volume booster with transmission ratio amplifies the outlet pressure at a 1:1 up to 1:6 ratio by a pneumatic pilot pressure, which has no constant bleed. That signal pressure has the same function as a spring in a common regulator: generating counter pressure on the diaphragm. This force is compensated by the outlet pressure on the diaphragm's bottom side. The ratio of pilot pressure to outlet pressure dépends on the size of the operating diaphragms. Media compressed air or non-corrosive gases Supply pressure max. 17 bar Pilot pressure max. 10 bar at 1:1 ratio, 5 bar at 1:2, - 3.3 bar at 1:3, - 1.7 bar at 1:6, pilot port G1/4 Accuracy at supply variation of 3.5 bar: < 7mbar1:1,< 10 mbar at 1:2, < 21 mbar at 1:3, < 41mbar at1:6 response sensitivity: - < 2 mbar 1:1, < - 3 mbar at 1:2, < 17 mbar at 1:3, < 23 mbar at 1:6 Air consumption max. 3 l/min. subject to outlet pressure Relieving function relieving Relief capacity 170 l/min at 1.5 bar outlet and 0.7 bar overpressure above setpoint Gauge port on both sides of the body. thread equal to regulator thread - Mounting position any Température range 0 °C to 70 °C / 32 °F to 158 °F, for appropriately conditioned compressed air down to -40 °C / -40 °F Material Body: zinc die-cast Elastomer: NBR/Buna-N Inner valve: brass and stainless Steel
