Close

The pneumatic proportional valve 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 valve via connector
pin number 5.

Pressure_transducer:
Open_transducers: 100 mbar, 500 mbar
Capsuled_transducers: 1 bar, 5 bar, 10 bar, 16 bar, 20 bar, 30 bar and 50 bar

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