1. What is the nominal pressure of valves?
The nominal pressure of valves refers to the pressure level marked on the valve, which refers to the maximum pressure that the valve can withstand under standard test conditions. The nominal pressure of valves is usually expressed in standards such as PN, Class, ANSI, such as PN10, Class150, etc.
2. What is working pressure?
Working pressure refers to the pressure that the valve withstands when it is actually working. In actual work, the pressure that the valve withstands is not only affected by the pressure of the medium, but also by factors such as the temperature, flow rate, and flow rate of the medium.
3. Design pressure
The design pressure is the maximum pressure designed to ensure the safe operation of the equipment. When designing the equipment, the designer needs to consider the safety of the equipment and determine the maximum pressure value based on the actual use of the equipment. The design pressure is usually the theoretical upper limit of the pressure that the equipment can withstand. In actual use, it is best to control the working pressure of the equipment below the design pressure to ensure the safe operation of the equipment.
The nominal pressure and design pressure of the valve are important parameters of the valve, which have a great impact on the use, maintenance and safety of the valve. If the nominal pressure and design pressure of the valve do not match, the valve may not work properly, leak or even explode. Therefore, when selecting and using valves, it is necessary to strictly follow the design requirements to ensure the matching of nominal pressure and design pressure.
