PN (maximum working pressure/nominal pressure) is a digital representation of stress-related code, is to provide the reference in a convenient rounded number, PN is approximate in the number of compression MPa at room temperature, is the nominal pressure valve usually use in China. Control valve for carbon steel body, refers to the application under 200 ℃ maximum allowable working pressure; For cast iron valve body, refers to the application under 120 ℃ when the maximum allowable working pressure; Control valve for stainless steel body, refers to the application under 250 ℃ maximum allowable working pressure. When the temperature rises, the pressure on the body decreases. American standard valve class as nominal pressure, the combination of the class is for a certain kind of metal calculation result of temperature and pressure, he calculated according to the standard ANSI B16.34. The pound and the nom
