The opening and closing part of the ball valve is used as a sphere, and the sphere is rotated 90o around the axis of the valve stem to achieve the purpose of opening and closing.
The ball valve is mainly used to cut off or connect the medium, and can also be used for fluid adjustment and control. The V-shaped ball valve can perform more accurate flow adjustment and control, and the three-way ball valve is used to distribute the medium and change the flow direction of the medium.
The ball valve is not only simple in structure, good in sealing performance, but also small in size, light in weight, low in material consumption, small in installation size, and small in driving torque within a certain nominal passage range. It is simple to operate and easy to achieve rapid opening and closing. The ball valve is One of the fastest growing valve varieties in the past ten years. The use of ball valves is very wide, and the variety and quantity of use continue to expand, and it is developing in the direction of high temperature, high pressure, large mouth, high sealing performance, long life, excellent adjustment performance and multi-function of a valve. Its reliability and other performance indicators All have reached a high level, and have partially replaced gate valves, globe valves, and throttle valves.
In the 2 flange ball valve structure produced by milestone valve company, the flange is connected by bolts, and the seal is made of reinforced polytetrafluoroethylene inlaid into the stainless steel ring. There is no spring at the back of the steel ring to ensure that the valve seat is close to the ball and keep the seal. There is no PTFE bearing on the upper and lower valve stems to reduce friction and save labor. There is no adjusting plate at the bottom of the small shaft to ensure the joint position between the ball and the sealing ring. 2 flanged ball valve is full diameter for pipeline cleaning.

The nominal diameter is same as the pipe diameter. the medium is linear flow, small resistance, more suitable for easy solidification, high viscosity liquid medium. The valve is more suitable for liquid of linear flow, low resistance, easy solidification and high viscosity.
