Valve Knowledge: Brass Ball Valve

Brass ball valve and plug valve are the same type of valve, only its closing part is a ball, the ball rotates around the center line of the valve body to achieve opening and closing of a valve. Brass ball valve is mainly used in the pipeline to cut off, distribute and change the flow direction of the medium. Brass ball valve is a new type of valve widely used in recent years. Brass ball valve and plug valve are the same type of valve. Only its closing part is a ball. The ball rotates around the center line of the valve body to achieve opening and closing. Kinds of valves.

Brass ball valve is mainly used in the pipeline to cut off, distribute and change the flow direction of the medium. Brass ball valve is a new type of valve widely used in recent years, it has the following advantages:

1. The fluid resistance is small, and the resistance coefficient is equal to that of the pipe section of the same length.

2. Simple structure, small size and light weight.

3. It is tight and reliable. At present, the sealing surface material of brass ball valve is widely used plastic and has good sealing performance. It has also been widely used in vacuum system.

4. 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.

5. The maintenance is convenient, the brass ball valve has a simple structure, the sealing ring is generally movable, and the disassembly and replacement are more convenient.

6. 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.

7. It has a wide range of applications, from small diameters to a few millimeters to a few meters, from high vacuum to high pressure.

Brass ball valves have been widely used in petroleum, chemical, power generation, papermaking, atomic energy, aviation, rockets and other departments, as well as people's daily lives.
