High Temperature High Pressure power plant gate valve
The model designation of the valves consists of seven units and their meanings are shown as the diagram below: Nominal pressure codesare indicated in Arabic numerals and their numerical values are ten times of nominal pressure values (unit: MPa). When the operationtemperature of valve medium exceeds 425'C, applies the indication of both maximum operating temperature and its correspondingoperating pressure, the order of the indication starts from P, its subscript marks its operating temperature (the value is shown as 1/10 of itsmaximum operatina temperature), rear mark is the ten times of the operatina pressure (unit. MPa), for example P54100.
