Volume pneumatic booster R750-0 series

pressure

The volume booster with transmission ratio amplifies the outlet pressure at a 1 to 1 up to 1 to 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 depends on the size of the operating diaphragms. Media: compressed air or non-corrosive gases Pilot_port: G1/4 Accuracy: at supply variation of 3.5 bar = < 7 mbar at 1 to 1, < 10 mbar at 1 to 2, < 21 mbar at 1 to 3,< 41 mbar at 1 to 6 Response_sensitivity: < 2 mbar at 1 to 1, < 3 mbar at 1 to 2, < 17 mbar at 1 to 3,< 23 mbar at 1 to 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 Temperature_range: 0 °C to 70 °C / 32 °F to 158 °F, for appropriately conditioned compressed air down to -40 °C / -40 °F Body: zinc die-cast Elastomer: NBR/Buna-N Inner_valve: brass and stainless steel
