Scope
This standard specifies the terms and definitions, ordering guidelines, technical requirements, materials, inspection and testing, quality certificates, marking, packaging, supply, and transportation for steam station temperature-reducing and pressure-reducing valves. This standard applies to temperature-reducing and pressure-reducing valves used in steam systems of power stations with a working pressure of P≤35 MPa and a working temperature of t≤625℃. Temperature-reducing and pressure-reducing valves used in steam systems of power stations with a working pressure of P≤35 MPa and a working temperature of t≤625℃, as well as temperature-reducing valves used in steam systems of power stations with a working temperature of t＞625℃, may be implemented in accordance with this standard.
