Ball valve is made up of cock. It has the same rotate 90 degrees to action, different is the cock body is ball, a round hole or channel through its axis. Spherical and opening ratio should be such, that is when the ball rotate 90 degrees, in the inlet and outlet should be completely present spherical, thereby blocking flow. Ball valve just has to rotate 90 degrees operation and small rotational torque can be closed tight. Full equality of the valve body cavity for medium resistance is very small, straight flow channel. Usually do think most suitable direct ball valve open and close, but recent development has put a ball valve designed to make it with throttling and control 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 a whole, also can be combined. Ball valve link url: WWW. zjxmfm。 com
