- Fixed Cone Valves (Hollow Jet Valves)
Nencini's fixed cone valve discharges water in free air, chamber or underwater level, controlling the flow with the movement of the valve sleeve.
This type of valve can be customized on demand and is particularly suitable for dissipating very high energy without cavitation when discharging in free air. If the water is discharged into the chamber or underwater, Nencini is able to design the pool or stilling basin, which are of primary importance for the effectiveness of the discharge and dissipation system.

Applications
The engineering know-how, the high-quality production and the custom installation on site, makes this kind of valves suitable for many different applications
- hydraulic power plants
- turbine by-pass
- controlled discharges
- automatic pressure surge relief
