V-ball is evolved from the stopcock. It has the same movement rotated 90 degrees to mention Weifang valve, cock body is different sphere, circular holes or channels through its axis. Sphere and the ratio of openings should be such that when the ball is rotated 90 degrees, in the import and export of office should be fully rendered sphere V-ball manufacturers, thereby cutting off the flow. Just use the rotary valve 90-degree operation and a small torque can be closed tightly. The body cavity of full equality for the media provided little resistance, through the flow channel. Generally considered the most suitable valve opening and closing done directly using V-ball, but the recent development has been designed to give it a throttle valve and flow control purposes. The main features of valve is its own compact, easy operation and maintenance for water, solvents, acids, and natural gas work in general media, but also for the poor working conditions of media, such as oxygen, hydrogen peroxide, methane and ethylene. Ball valve can be integral, or may be modular. The main features of V-ball are as follows: (1) switch quickly and easily (2) sealing Currently, the vast majority of valve seat are made in V-ball vendors, metal and clap elastic material such as polytetrafluoroethylene Sealing metal material, often referred to as soft seal. In general, the soft seal tightness easily guaranteed, and the sealing surface of the machining accuracy and surface roughness requirements are not very high.
