Proportional control valve »posiflow«, 24 V DC, NC, G 1/4, DN 3.2

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
