The three-piece stainless steel ball valve only needs to be rotated 90 degrees and small rotational torque to close the tight. The fully equal body cavity provides a small, straight flow path for the medium. Ball valves are generally considered to be the most suitable for direct closure, but recent developments have designed the ball valve to be used for throttling and controlling flow. Ball valve itself is the main characteristics of compact structure, easy operation and maintenance, and is applicable to water, solvent, acid and gas, such as general work medium, but also is suitable for the working conditions of media, such as oxygen, hydrogen peroxide, methane and ethylene. Ball valve body can be integral, also can be combination type.
It has the following characteristics:
1.The fluid resistance is small and its drag coefficient is equal to that of the same length.
2.Simple structure, small size and light weight.
3.Close and reliable, the sealing material of ball valve is widely used in plastic and sealing, and it is widely used in vacuum system.
4.Easy to operate, open and close quickly, from open to close just rotate 90°, is advantageous for the remote control.
5.Easy to maintain, the ball valve structure is simple, the sealing ring is generally active, disassembly and replacement are more convenient.
6.The sealing surface of the ball and seat is separated from the medium in full open or closed. When the medium is passed, the sealing surface of the valve will not be eroded.
7.Wide range of applications, ranging from small to several millimeters, large to several meters, from high vacuum to high pressure can be applied.
The three-piece stainless steel ball valve is a new type of ball valve. It has some advantages peculiar to its own structure, such as no friction on the switch, not easy to wear, and small opening and closing moment.This reduces the specification of the matched actuator. With multi-rotating electric actuator, the medium can be adjusted and cut tightly. It is widely used in oil, chemical industry, urban water supply and drainage, etc.
