Pipeline valve - Import export

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.

The valve avoids reservoir emptying and flooding dues to casual pipeline failure. The valve is controlled by a differential hydraulic pilot that senses flow speed closing completely main flow when senses critical speed values.
