Specifications 101644

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
