Applicable Occasions of Ball Valve

Since the ball valve移动暴龙捕鱼 usually use rubber, nylon and Teflon as a valve seat ring material, so its use temperature is limited.Closing action of valve is pressed between the plastic seat to complete by metal spheres in the role of the media. Valve seat ring at a certain contact pressure, elastic-plastic deformation occurs in some areas. This deformation can compensate for manufacturing precision and surface roughness of the sphere, to ensure valve sealing performance.

Due to ball valve seat ring is usually made of plastic, so the choice of structure and properties of ball valve, to consider the ball valve of fire and fire prevention, especially in the petroleum, chemical, metallurgy and other sectors.

Typically, the piping system of two-position adjustment, strict sealing, mud, wear, necking channel, opening and closing action quickly, high voltage cut-off, low noise, there is the phenomenon of cavitation and gasification, the operating torque, fluid resistance recommended ball valve.
