R03-J

Description:
Pilot-operated volume booster with positive bias designed to supply
outlet pressure equal to signal pressure plus an adjustable preset
spring constant. With very high forward and reverse flow characteristics
and excellent sensitivity. A typical application is balancing
or regulating pressure in tanks.

Media: oil-free and 5 µm filtered compressed air or non-corrosive gases

Supply_pressure: max. 16 bar
Ratio: 1:1
Pilot_pressure:
max. 10 bar, accordingly lower in the case of manual pre-pressure setting,
pilot port G1/8

Accuracy:
at supply pressure change from 2 bar to 7 bar
= < 6 mbar pressure deviation
at flow rate change from 0 l/min to 20 l/min
= < 20 mbar pressure deviation
response sensitivity = < 2 mbar

Air_consumption:
1.5 l/min at P1= 5 bar,
2 l/min at P1= 7 bar,
4 l/min at P1= 10 bar, < 1% of volume flow

Relieving_function: relieving, tapped exhaust
Relief_capacity: 700 l/min at 6 bar outlet and 0.35 bar overpressure above setpoint
Gauge_port: G1/4 on both sides of the body, one screw plug supplied
Mounting_position: any

Temperature_range:
0 °C to 60 °C / 32 °F to 140 °F, for appropriately conditioned compressed air down to -30 °C / -22 °F

Body: zinc die-cast
Elastomer: NBR/Buna-N
