Pressure Value
Use Arabic number to Figure nominal pressure, and numerical value is ten double working pressure value regard MPa as unit, but the numerical value of Power station valve which is used for high pressure and temperature conditions is real working pressure value regard MPa as unit.
Power station valve Pressure value:
Nominal pressure unit : MPa
When fluid temperature =450degree C,figure the real nominal pressure.
When fluid temperature >450degree C,figure working temperature and pressure.
Figure as follow examples:
Pw5410 : P – pressure ,
w54 – working temperature 540degree C, 10 – working pressure 10 MPa.
