Compressed air pressure regulator R208

for inert gasesmembranesingle-stage

Description 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 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, - 2.5 bar at 1:4, - 1.7 bar at 1:6 Pilot port G1/4 Accuracy at supply pressure variation of 7 bar: < 7 mbar pressure déviation transmission error: - 1% from 1:1 to 1:3 ratio. 2% at greater or inverse transmission response sensitivity: - 1 mbar at 1:1, 2 mbar at 12, 3 mbar at 1:3 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 Température 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 Material Body:aluminium die-cast - Elastomer: NBR/Buna-N. optionaly FKM Inner valve: brass and zinc-plated Steel
