Dec 02, 2016

The principle of ball valve. Ball valve works by rotating the valve core to make the valve open or blocked. Ball valve switch light, small size, can be made of large diameter, reliable sealing, simple structure, easy maintenance, sealing surface and spherical surface is often closed, not easily eroded by the media in various industries has been widely used.

The advantages of the ball valve. Ball valve in the pipeline is mainly used to do cutting, distribution and change the direction of flow of media. Ball valve is widely used in recent years, a new type of valve, which has the following advantages: small fluid resistance, the resistance coefficient and the same length of the pipe section is equal; simple structure, small size, light weight; close reliable ball valve sealing surface material Wide use of plastic, good sealing, in the vacuum system has also been widely used; Easy to operate, open and close quickly, from full open to fully closed as long as the rotation 90 °, easy remote control; easy maintenance, simple structure, Generally are active, the demolition and replacement are more convenient; in full or full closure, the ball and seat sealing surface and medium isolation, the media through, it will not cause corrosion of the valve sealing surface; wide range of applications, diameter From small to a few millimeters, large to a few meters, from high vacuum to high pressure can be applied.
