Product Description

Ball valve after more than half a century of development, now has become a widely used main valve class.The main function of the ball valve is to cut off and connect the fluid in the pipeline;It can also be used for fluid regulation and control.Ball valve has the characteristics of small flow resistance, good sealing, quick switching and high reliability.

Ball valve is mainly composed of valve body, valve cover, valve stem, ball and sealing ring and other parts, belongs to 90.Switch off valve, it with the help of the handle or driving device in the upper end of the stem to apply a certain torque and transfer to the ball valve, so that it rotates 90°, the ball through hole and the valve body channel center line overlap or vertical, complete the full open or full close action.Generally there are floating ball valves, fixed ball valves, multi-channel ball valves, V ball valves, ball valves, jacketed ball valves and so on.It can be used for handle drive, turbine drive, electric, pneumatic, hydraulic, gas-liquid linkage and electric hydraulic linkage.
