發(fā)布時(shí)間:2022-07-14瀏覽量:0

When choosing a stainless steel flanged ball valve, it is necessary to choose the right model, to be able to understand each performance parameter in detail, and then to select or customize according to the specific parameters, otherwise there will be relatively big mistakes in later use.

    First of all, it is necessary to determine the working pressure of the stainless steel flanged ball valve, especially the pressure generated when the valve is closed. The user must determine how much pressure the stainless steel flanged ball valve he purchased can withstand. More able to choose the correct valve size to adapt to this pressure, will not damage the valve.

    Then it is necessary to determine what the temperature of the medium flowing through this valve is. Under normal circumstances, it is necessary to consider whether the valve can withstand the temperature of the medium. Every different material, such as ceramics, stainless steel, etc., will be used in the manufacture of the valve.

    Specific fluid control systems need to be designed for the control of different fluids. For example, some special designs are applied to radioactive substances to ensure that the valve does not leak.
