What is the working principle of pneumatic valve

Pneumatic valve body is made up of one variation of plug valve, its heart is ° rotating movement, body body centerline as rotate to open, has a circular hole or channel through its axis. Beware of rotation to ° when the valve is in closed state, when the actuators work, just a small rotational torque to the valve shut tightly, which can achieve fast truncation to cut off the principle. Pneumatic valve is mainly used in fast cutting, distribution, and change the flow of the medium in the pipeline. The v-shaped body can accurately adjust the medium flow. Pneumatic valves open and close quickly, it is suitable for the size of the diameter. There are two kinds of pneumatic valve structure, one kind is V type core, it USES a fixed structure, core with v-shaped incision, after adding locator on actuator for fiber ratio control, granular media. Another is O, O for precision casting, valve core flow crossing the same as the pipe size, is mainly used as truncation switch.
