R40
Choose a version from the table underneath, please.
Description:
Highly sensitive, two-step precision pressure regulator working
in the flapper-nozzle principle. Solid construction for
low-maintenance operation with compressed air or non-corrosive gases.
Booster_version:
In option A version the regulator can also be controlled by
pilot pressure up to 7 bar in addition to range spring control.
Thereby the regulator becomes a volume booster with double loop,
parallel zero point shift
Supply_pressure:
minimum: 0.3 bar above outlet pressure
maximum: see chart
Air_consumption:
Constant bleed only when flow is circulating. The greater the
difference between supply and outlet pressure the greater is
the air consumption, e.g. 9 bar inlet and 7 bar outlet
resulting in 3 l/min air consumption.
Exhaust:
50 l/min at 1.7 bar outlet pressure and 20 mbar overpressure to outlet pressure
Pressure_stability: 10 mbar pressure drop when changing flow rate from "0" to "max".
Setting_accuracy: < 0.03 % outlet pressure. Ten adjusting knob turns for the setting of the whole adjustment range.
Gauge_port: 1⁄4˝ NPT on both sides, screw plugs supplied
Temperature_range:
Operating pressure = -4 °C to 80 °C / 25 °F to 176 °F
Storage temperature= -20 °C to 100 °C / -4 °F to 212 °F
Temperature_sensitivity:
1 % pressure deviation at temperature change of 30 °C
Material_fluid_contact: brass, stainless steel, neoprene, aluminium and zinc
