Hydroelectric ball valve,ball valve

The water and electricity ball valve adopts an upper-mounted structure design. The valve body material can be selected as QT450/WCB material. Flange connection. Drive mode: electric. Nominal pressure: PN6-16. Nominal diameter: DN200-DN2400. Medium used: water. Temperature range: The temperature is ≤150℃. The sealing surface is surfacing with stainless steel material, which is corrosion-resistant and has a long service life. The eccentric structure design ensures no friction during opening and closing, providing excellent sealing performance. It is widely used as a connecting and shut-off valve in water supply and drainage pipelines of hydropower stations, waterworks, reservoirs, etc.

By using the eccentric valve body, eccentric ball and valve seat, the valve stem automatically centers along a common trajectory when rotating. During the closing process, it closes tighter and tighter, fully achieving excellent sealing performance. The ball and the valve seat of the valve are completely separated, eliminating the wear of the sealing ring and overcoming the problem of constant wear between the traditional ball valve seat and the ball sealing surface. The non-metallic elastic material is embedded in the metal seat, and the metal surface of the valve seat is well protected.
