The classification of the pneumatic valve

according to the function of the pneumatic valve without, instrument pneumatic valve can be divided into the following categories:
according to use can be divided into: truncation pneumatic pneumatic valve, safety valve, check valve, pneumatic valve, shunt valve adjustment.
in use according to its different nominal pressure can be divided into: vacuum pneumatic valve, low pressure pneumatic valve, medium pressure pneumatic valve, pneumatic valve, high-pressure ultra-high pressure pneumatic valve.
according to the working temperature of normal use classification can be divided into: cryogenic pneumatic valve, pneumatic valve, pneumatic valve at room temperature at low temperature, high temperature medium temperature pneumatic valve, pneumatic valve.
according to the different methods of braking can be divided into: automatic pneumatic valve, pneumatic valve is divided into ( Safety and pneumatic valve, relief valve, hydrophobic pneumatic valve, check valve, the automatic regulating pneumatic valve) ； Drive, pneumatic valve, drive pneumatic valve can also be according to the different power sources are divided into ( Electric pneumatic valve, pneumatic valve, pneumatic hydraulic pneumatic valve, pneumatic pneumatic valve, electric pneumatic valve) Pneumatic valve, manual.
according to the diameter of the fluid through the instrument pneumatic valve size can be divided into: small size instrument pneumatic valve, its diameter instrument instrument pneumatic valve, pneumatic valve, bore diameter super-large size instrument pneumatic valve.
different shapes according to the instrument of the pneumatic valve structure can be divided into: door, cock, cock kai xuan pneumatic valve, pneumatic valve, butterfly line, smooth pneumatic valve.
in accordance with the instrument pneumatic valve is different from other pipe connection mode can be divided into: threaded connection instrument pneumatic valve, pneumatic valve, welding connection flange connection instrument instrument pneumatic valve, pneumatic clamp connection instrument valve, card sets of connecting instrument pneumatic valve, pneumatic valve connected to the clamp meter.
according to manufacturing the materials can be divided into pneumatic valve use instrument; Metal material instrument pneumatic valve, non-metallic materials instrument pneumatic valve, pneumatic valve body metal lining instrument pneumatic valve.
instrument pneumatic valve models of various kinds of too much and there may be other types of classification, but ultimately apply industrial pipes with the pneumatic brake valve, throttle pneumatic valves, pneumatic ball valve, butterfly valve, pneumatic diaphragm valve, pneumatic valve, plunger cock pneumatic pneumatic valve, safety valve, check valve, vacuum pneumatic valve, drain valve etc.
