Stainless steel ball valve is a type of ball valve, widely used in various industries. The working principle is not very complicated, and it is necessary to rely on the rotary valve core to make the valve open or blocked. The ball valve is light and compact, and it can be made into a large diameter, reliable sealing, simple structure, and easy maintenance. The sealing surface and the spherical surface are often in a closed state and are not easily eroded by the medium.
1. The fluid resistance is small, and the resistance coefficient is equal to that of the same length.
2, simple structure, small size, light weight.
3, close and reliable, the ball valve sealing surface materials are widely used plastic, good sealing, has also been widely used in the vacuum system.
4, easy to operate, open and close quickly, from full open to full off as long as the rotation 90 °, easy to control the distance.
5, easy maintenance, ball valve structure is simple, the seal ring is generally active, removal and replacement are more convenient.
6. When fully open or fully closed, the sealing surfaces of the ball body and the valve seat are isolated from the medium. When the medium passes through, the sealing surface of the valve will not be eroded.
7, a wide range of applications, from a small diameter to a few millimeters, up to a few meters, from high vacuum to high pressure can be applied.
Ball valve has been widely used in petroleum, chemical, power generation, paper, atomic energy, aviation, rockets and other departments, as well as people's daily lives.
