Classification of instrument valve

Not according to the Instrument needle valve valve instrument valve function, can be divided into the following categories:
By end use can be divided into: cut-off valve, check valve, safety valve, regulating valve, diverter valve.
According to its use in the nominal pressure can be divided into: vacuum valve, low pressure valve, the pressure valve, high pressure valves, high pressure valve.
According to the normal use of the working temperature of classification can be divided into: ultra-low temperature valve, cryogenic valves, valve, normal temperature valve, high temperature valve.
According to different braking modes can be divided into: automatic valve, automatic valve is divided into (safety valve, pressure reducing valve, drain valve, check valve, automatic control valve); to drive the valve, to drive the valve can also be divided according to different power source (electric valve, pneumatic valve, hydraulic valve, pneumatic valve electric valve, manual valve,).
According to the fluid through the Instrumentation ball valve diameter size can be divided into: small diameter instrument valves, diameter instrument valves, large diameter, large diameter instrument valves instrument valves.
According to the structure of instrument valves of different shapes can be divided into: valve shape, cock shaped, plug valve, rotary valve, butterfly valve line, line.
According to the connection mode of instrument valves and other fittings can be divided into: the threaded connection, flange connection Instrument Valves instrument valves, instrument valve, welded connection clamp connection instrument valves, the card sets of connections instrument valves, instrument valves on the clip connection.
According to manufacturing the used instrument valve material is divided into; metal materials, non-metallic materials instrument valves Instrument Valves instrument valves, metal body lining.
Instrument valves of all kinds of too much may have other kinds of classification, but it is still used for industrial pipe valve, throttle valve, ball valve, butterfly valve, diaphragm valve, plunger valve, plug valve, check valve, safety valve, relief valve, drain valve etc..
