According to the different functions of instrument valves, which types can they be divided into
According to the different functions of instrument valves, they can be divided into the following categories:
According to the use can be divided into: block valve, check valve, safety valve, control valve, diverter valve.
According to the different nominal pressure in use, it can be divided into vacuum valve, low pressure valve, medium pressure valve, high pressure valve and ultra-high pressure valve.
According to the classification of working temperature in normal use, it can be divided into ultra-low temperature valve, low temperature valve, normal temperature valve, medium temperature valve and high temperature valve.
According to different braking modes, it can be divided into automatic valve and automatic valve (safety valve, pressure reducing valve, drain valve, check valve and automatic regulating valve); The driving valve can also be divided into electric valve, pneumatic valve, hydraulic valve and manual valve according to different power sources.
According to the diameter of the fluid through the instrument valve can be divided into: small diameter instrument valve, medium diameter instrument valve, large diameter instrument valve, large diameter instrument valve.
According to the different structure and shape of instrument valve, it can be divided into: gate type, plug type, plug type, swing type, butterfly type and slide type.
According to the different connection ways of instrument valve and other pipe fittings, it can be divided into: threaded instrument valve, flange instrument valve, welded instrument valve, clamp instrument valve, sleeve instrument valve and clamp instrument valve.
According to the materials used in the manufacture of instrument valves, they are divided into three parts; Metal material instrument valve, non-metal material instrument valve, metal body lined instrument valve.
There are too many types of instrument valves, and there may be other classifications, but they are still suitable for gate valves, throttle valves, ball valves, butterfly valves, diaphragm valves, plunger valves, plug valves, check valves, safety valves, pressure reducing valves, and steam traps used in industrial pipelines.
