For electronic flow control

For all applications where the flow rate of a liquid or gas has to be controlled.
The valve features a special magnet armature and is
characterised by low friction and a high dynamic response.

If the valve is combined with a plug amplifier:
The maximum / minimum current and frequency can be adjusted by
means of integrated potentiometers.
A current ramp can also be connected and adjusted with a potentiometer.
This facilitates a slow change in the flow rate, even if the setpoint
changes suddenly.
If the setpoint is < 200 mV (< 0.4 / 4.4 mA), the piloting current is completely
switched off, causing the valve to be de-energised (tightly closed function).

We recommend combining these proportional valves with a plug amplifier,
type PV 2910 or PV 2920

For converting the 0 to 10 V, 0 to 20 mA or 4 to 20 mA standard signal (settable)
to an impressed current (0 to 1 A).
The impressed current is pulse width modulated to ensure low-hysteresis,
thermally stable control.
With settable time ramp (ON/OFF, 0.1 to 3 s).
The minimum and maximum supply current for the solenoid can be set according to
the control signals.
