Air pneumatic ball valve technical parameters overview

air pneumatic ball valve technical parameters overview
steam source pneumatic ball valve is a kind of can be precise adjustment of pneumatic valves, for flammable and explosive, toxic or radioactive medium, leakage is not allowed, so instrument pneumatic valve must have a reliable sealing performance.
air pneumatic ball valve USES the
steam source pneumatic ball valve USES broad, such as flame cutting with the cutting distance, flame temperature adjustment knob is air pneumatic ball valve. Air supply pneumatic ball 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.
