Products Description
The stainless steel two-piece ball valve and the flange gate valve are the same type of valve. The difference is that the closing part is a ball. The ball rotates around the center line of the valve body to achieve opening and closing. The ball valve is mainly used in the pipeline to cut off, distribute and change the flow direction of the medium. The two-piece ball valve and the three-piece ball valve are a new type of valve widely used in recent years.
The fluid resistance is small, and the resistance coefficient is equal to that of the pipe section of the same length. Simple structure, small size and light weight. It is tight and reliable. At present, the sealing surface materials of ball valves are widely used with plastics and have good sealing performance. It is easy to operate and quick to open and close. It only needs to rotate 90 ° from fully open to fully closed to facilitate remote control. The maintenance is convenient, the structure of the ball valve is simple, the sealing ring is generally movable, and the disassembly and replacement are more convenient. When fully open or fully closed, the sealing surfaces of the ball and the valve seat are isolated from the medium. When the medium passes through, it will not cause corrosion of the valve sealing surface.
It has a wide range of applications, from small diameters to a few millimeters to a few meters, from high vacuum to high pressure.
The stainless steel two-piece ball valve can be divided into straight-through type, three-way type and right-angle type according to its channel position. The latter two kinds of ball valves are used to distribute the medium and change the flow direction of the medium. Stainless steel two-piece ball valve
