Volume pneumatic booster R208-2 series

pressure

The volume booster amplifies the volume at a 1 to 1 ratio of pilot pressure to outlet pressure. The pilot pressure has no constant bleed and shows the same function as a spring in a common regulator. Generating counter pressure on the diaphragm. Media: compressed air or non-corrosive gases Response_sensitivity: 1 mbar at 1 to 1, 2 mbar at 1 to 2, 3 mbar at 1 to 3 and at inverse transmission Air_consumption: max. 3 l/min, subject to outlet pressure Relieving_function: relieving Relief_capacity: 310 l/min at 1.5 bar outlet and 0.35 bar overpressure above setpoint Gauge_port: G1/4 on both sides of the body, screw plugs supplied Mounting_position: any Temperature_range: 0 °C to 80 °C / 32 °F to 176 °F, NBR, for appropriately conditioned compr. air down to -40 °C / -40 °F 0 °C to 90 °C / 32 °F to 194 °F, FKM, for appropriately conditioned compr. air down to -40 °C / -40 °F Body: aluminium die-cast Elastomer: NBR/Buna-N, optionally FKM Inner_valve: brass and zinc-plated steel
