Aug 10, 2016

By main parameters

According to the nominal pressure

(1) vacuum valve: working pressure lower than normal atmospheric pressure of the valve.

(2) low pressure valve: refer to valves of nominal pressure PN ≤ 1.6Mpa.

(3) pressure relief valve: refer to nominal pressure PN 2.5Mpa, 4.0Mpa, 6.4Mpa valve.

(4) high pressure valve: the nominal pressure PN 10.0Mpa~80.0Mpa valve.

(5) high pressure valve: the nominal pressure PN ≥ 100.0Mpa valve.

Working temperature

(1) cryogenic valve: valve used in medium temperature t<-101 ℃.

(2) temperature valve: for medium working temperature-29 c <t<120 valves.

(3) temperature valve: valve used for medium temperature 120 ¡æ <t<425 ¡æ.

(4) high temperature valves for medium working temperature t>425 valve.
