Valves Classified By Nominal Pressure

- Apr 18, 2017-

(1) Vacuum valves: valves That work pressure below the standard atmosphere.

(2) Low-Pressure valve: refers to the nominal pressure pn ≤ 1.6Mpa valves.

(3) Medium pressure valve: Refers to the nominal pressure pn is 2.5Mpa, 4.0MPA, 6.4MPA valve.

(4) High-pressure valve: refers to the pressure PN as the 10.0Mpa~80.0Mpa valve.
