Fixed cone valve

pinchmanualelectrically-operated

The discharge of the flow is controlled by the movement of the sleeve of the valve against the fixed cone. The fixed cone valve discharges the raw water of dams to free air, chamber or underwater level. This valve is especially suitable to dissipate very high energy without any cavitation when discharge is made into free air. In the case when the water is discharged into chamber or underwater, Nencini is capable of designing the stilling pool or basin which are of primary importance for the effectiveness of the discharging and dissipation system. Applications : ■ hydraulic power plants ■ turbine by-pass ■ controlled discharges ■ automatic pressure surge relief.
