The working principle of pneumatic needle type pneumatic valve

any pneumatic valve action for cutting fluid. Depending on the pneumatic valve core, can be divided into the pneumatic valve, pneumatic valve, cock pneumatic brake valve, pneumatic ball valve, pneumatic valve, needle type pneumatic butterfly valve and so on. 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 are threaded connections. Pneumatic pneumatic valve needle, the needle type pneumatic valve, pneumatic valve is a kind of can accurate adjustment, the widely used, 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 purpose is for open or cut off the pipeline path. Needle type pneumatic valve pneumatic valve core is a very sharp cone, like needle inserted into the pneumatic valve seat, hence the name.
