Scope
This standard specifies the classification, requirements, test methods, inspection rules, marking, and supply requirements for iron-made shut-off valves and lifting check valves. This standard applies to iron-made shut-off valves and lifting check valves with nominal pressures of PN10 to PN16, nominal sizes of DN15 to DN200, and applicable temperatures not exceeding 200°C, which are connected by internal thread and flange. This standard also applies to throttle valves.
