1, pneumatic valve: It is evolved from the cut-off valve. It has the same rotation of 90 degrees movement, difference is that cock body is a sphere, a circular hole or pass
Road, through its axis. The sphere and the ratio of openings should be such that when the ball rotated 90 degrees, in the import and export office should be fully rendered sphere, and thus cut-off
Off flow. This type valve in the pipe can be installed anywhere.
2, Ming precision pneumatic valve: just use the pneumatic air supply Used for the implementation of the operation of rotating 90 degrees and a small rotational torque can be closed tightly. Full equality
The body cavity for the medium offers little resistance, through the flow channel. Generally considered the most suitable valve opening and closing done directly used, but recent developments have ball valve
Is designed to make it flow with the throttle and control purposes. The main features of valve is its own compact, easy operation and maintenance for water, solvents, acids
And gas work in general media, but also applies to poor working conditions of media, such as oxygen, hydrogen peroxide, methane and ethylene and so on. Ball valve can be
Take the present as a whole, it can be modular.
