Relationship between Nominal Pressure and Rated Operating Pressure of Valves

1.What is valve nominal pressure?

Valve nominal pressure refers to the pressure level specified by the valve size and design standards. It is one of the important size parameters of the valve and is usually marked as PN. Rated operating pressure refers to the pressure range of the valve during normal operation and is also one of the standards for evaluating valve performance and reliability.

2.What is the relationship between nominal pressure and rated operating pressure?

The valve nominal pressure and rated operating pressure have close relationship. The nominal pressure is selected according to the valve size and design pressure level, representing the design pressure level of the valve, while the rated operating pressure is the pressure range that the valve can withstand in actual work. Specifically, when the operating pressure of the valve is less than or equal to its nominal pressure, the valve can work normally, otherwise it cannot.

3.What is the role of valve nominal pressure and rated operating pressure in actual applications?

The nominal pressure and rated operating pressure of the valve are one of the main indicators for evaluating valve performance and reliability. In the practical applications, we need to choose the nominal pressure and rated operating pressure of the valve that meet the actual needs according to the specific situation. At the same time, the nominal pressure and rated operating pressure are also very important factors that must be considered in equipment design and operation.

Conclusively, the nominal pressure and rated operating pressure of the valve are important indicators of valve performance and reliability, and are of great significance for the selection, design, and operation of the valve fluid control system. In practical applications, it is necessary to comprehensively consider multiple indicators such as the nominal pressure and rated operating pressure to select the appropriate valves to meet actual needs.
