Pressure gauge as pneumatic valve

JW/H pressure gauge as pneumatic valve is a kind of can adjust the precision pneumatic valve USES broad, such as flame cutting with the cutting distance, flame temperature adjustment knob is needle type pneumatic valve, instrument needle type pneumatic valve is an important part of the meter in the piping system, mainly by the pneumatic valve and ball valve, its function is used as open or cut off the pipeline path. Any pneumatic valve action for cutting fluid. Depending on the pneumatic valve core, can be divided into pneumatic valve, pneumatic valve gate, cock pneumatic valve, pneumatic ball valve, pneumatic valve disc, needle type pneumatic valve and so on. Needle type pneumatic valve pneumatic valve core is a very sharp cone, like needle inserted into the pneumatic valve seat, hence the name. Needle type pneumatic valve form than other types of pneumatic valves that can tolerate more pressure, sealed performance is good, so generally used for small flow, high pressure gas or liquid medium sealing, needle type pneumatic valve and pressure gauge is used the most suitable, general type pneumatic valve needle shape is threaded connections. （ According to the pneumatic valve micro Po number)
