The valve pressure class conversion of Mpa,LB,K,bar
PN, Class, K, bar are all units of pressure rating to express the nominal pressure rating for pipelines, valves, flanges, pipe fittings or fittings. The difference is that the pressure they represent corresponds to different reference temperatures. PN refers to the corresponding pressure at 120℃, while CLass refers to the corresponding pressure at 425.5℃. Therefore, […]
