How much pressure can the high pressure ball valve withstand

Author:tongda Popularity: Issuing time:2018-07-19 17:49

The ball valve body may be integral or combined. The main features of the high-pressure ball valve are its compact structure, reliable sealing, simple structure and convenient maintenance. The sealing surface and the spherical surface are often closed, which is not easily eroded by the medium, and is easy to operate and maintain. High-pressure ball valves are suitable for general working media such as water, solvents, acids and natural gas, and are also suitable for mediums with harsh working conditions, such as oxygen, hydrogen peroxide, methane and ethylene, which are widely used in various industries.


1. How are the pressures of ultra-high pressure valves, high pressure valves, medium pressure valves and low pressure valves differentiated?
Ultra high pressure valve, nominal pressure PN≥100Mpa; high pressure valve, nominal pressure PN≥10.0Mpa-80.0Mpa; medium pressure valve, nominal pressure PN2.5Mpa-6.4Mpa; low pressure valve, nominal pressure PN≤1.6Mpa.
2. How are the calibers of large-diameter valves, large-diameter valves, medium-diameter valves, and small-diameter valves?
Extra large diameter valve, nominal size DN ≥ 1400mm; large diameter valve, nominal size DN350-1200mm; medium diameter valve, nominal size DN50mm-300mm; small diameter valve, nominal size DN ≤ 40mm. General ball valve, at a nominal pressure ≥ 100 pressure (10Mpa), is considered a high pressure. The 16 nominal pressure can be called normal pressure and 25 pressure.
