Product Features

1. Ball valve fluid resistance small, lining wall smooth, flow channel unobstructed is fluid resistance valve class of all the smallest one. 
2. The switch is rapid and convenient, just put the ball rotated 90 °, and complete the account opening and closing action. 
3. The use of special moulding process, to lining in the valve shell inner wall lining materials, can the corrosion of strong acid, strong alkali medium. lining spherical combined with PTFE seat, sealed well, achieve zero leakage. 
4. Can be configured pneumatic, electric, hydraulic and other drive, realize remote control and automation. 
5. The spheroid and the valve stem, eliminates the rotation Angle difference, put an end to the stem out of the danger of in vitro caused by pressure changes, to ensure the use of safety, reliability.
