The pneumatic proportional pressure regulator controls the outlet pressure in proportion to an electrical
command input signal. It comprises a complete closed loop servo system in a compact monoblock assembly with proportional solenoid valve, electronic regulator and internal pressure transducer.

In the process, the outlet pressure is transformed into a proportional electrical signal and compared
with the input signal. If the outlet pressure exceeds the preset setpoint, the valve exhausts down to the
pressure desired.

The valve has no constant bleed. At absence of input signal or supply voltage the valve exhausts.
The power supply of the setpoint potentiometer is provided by the proportional regulator
via connector pin number 5.

Pressure transducer:
Open transducers = 100 mbar, 500 mbar, 1/5/10/16/20/30/50 bar and vacuum

Application examples:
Proportional pressure regulators are being used for blowing machines, ultrasonic equipments, testing
machines, painting systems, contouring systems, laser welding machines, textile machines, cheese
presses, pneumatic brakes, clamping devices and medical engineering.
