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
mono block assembly with proportional solenoid valve, electronic
regulatior and internal pressure transducer. The valve works
as a 3-port/2-way valve with proportional magnet. The digital
control system offers advantages at installation and commissioning
for adapting the valve to special applications. The regulator can
be set and optimised using a PC, RS232 adapter and software. Data
record can be saved and used for further valves. The valve has no
constant bleed. At absence of input signal or supply voltage the
valve exhausts.

Software:
Display: signal, outlet pressure, parameter, pressure switch signal etc.
Scope function: view setpoint, outlet pressure, internal signals from PID control
Parameters: command signal, zero point, overload threshold, ramp
Valve diagnosis: parameters factory set or customised, optimization of the valve
