This series comprises valves with two connections that are operated by an electric motor. They are characterized by the fact that the valve stroke can be adjusted steplessly and held in place by a motor using a setpoint signal (420 mA or 010 V). This makes this series particularly suitable for precise dosing applications, as the servo motor reliably processes setpoint deviations of 1%.

The valve controls downstream flow to a pre-set and constant value in order to limit water consumptions and preserve pipeline fill rate or to set a maximum demand value. The valve is controlled by a differential hydraulic pilot that senses the pressure fall generated by water flow into a calibrated orifice.
