Judging the quality of the plug valve can be evaluated from the following aspects:
OneMaterial Quality:
The main material of the plug valve is generally cast iron, stainless steel, copper alloy, etc., and the quality of the material directly affects the corrosion resistance and service life of the valve.
IISealing performance:
The sealing performance of the plug valve mainly refers to the sealing effect between the valve and the sealed pipeline when the valve is closed, which can be judged by checking whether there is obvious leakage after the valve is closed.
IIIFluid Flow Capacity:
The fluid flow capacity of the plug valve indicates whether the valve can smoothly control the flow of fluid, which can be judged by the flow coefficient (CV value) of the valve.
FourthOperational Performance:
The operational performance of the plug valve refers to the flexibility of the operating handle or handwheel, the amount of operating force, etc., which can be evaluated by actual operation.
FiveApplicable conditions:
Plug valves generally have different models and specifications, and the appropriate plug valve should be selected according to the actual use conditions, such as pressure, temperature, medium, etc.
Considering the above factors, you can judge the quality of a plug valve. In addition, you can also refer to the credibility and product quality certification of Detersen manufacturers.
