Proportional control valve »posiflow«, for air / gas, 24 V DC, NC, G 3/8, DN 7.1, Operating pressure difference max. 1 bar
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.

Benefits:
- Compact and economical
- Integrated temperature compensation
- Precise control
- Optimised flow with no water hammer
- Ramp function assures a smooth response to step changes in the input signal
- Disconnect function
