R750

Your are now in the overview of an article: R750
Choose a version from the table underneath, please.

Description:
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
Supply_pressure: max. 17 bar

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
