Valve press classification

Vacuum valve - valve with working pressure lower than standard atmospheric pressure.

Low pressure valve - nominal pressure PN less than 1.6MPa valve.

Medium pressure valve - nominal pressure PN 2.5 ~ 6.4MPa valve.

High pressure valve - nominal pressure PN10.0 ~ 80.0MPa valve.

Ultra-high pressure valve - Nominal pressure PN greater than 100MPa valve.

Sort by media temperature

High temperature valve - valves greater than 450'C.

Temperature valve-120'C≤t≤450'C valve.

Room temperature valve - 40'C≤t≤120 'C valve.

Low temperature valve - 100'C≤t≤-40 'C valve.

Ultra low temperature valve - less than -100 'C valve.

Classification by valve body material

Metal valves, steel valves, stainless steel valves, alloy steel valves, cast iron valves, titanium alloy valves, Monel alloy valves, copper alloy valves, aluminum alloy valves, lead alloy valves.

Metal valve lining valve - such as lining fluorine valve, rubber lined valve, lining valve, lining the lead valve, lining enamel valve.

Non-metallic materials valves - such as ceramic valves, glass steel valves, plastic valves.
