Description

Nencini designs and produces Double Flanged Sleeve Valves. They allow a very high upstream pressure loss, without any risk of critical phenomena (cavitation, vibration, noise) even with little downstream head pressure. They are also used as synchronous discharge tool for turbine plants (mainly Pelton or Francis turbines) because they are able to work in high pressure condition. The discharge is carried out under high head loss across of the valve. Applications ■ hydraulic power plants.
