Valve purchase -technical requirements that must know
Valve working pressure is required to be greater than or equal to the working pressure of the pipeline. Under the premise of not affecting the price, the working pressure that the valve can withstand should be greater than the actual working pressure of the pipeline; any side of the valve should be able to withstand 1.1 times the working pressure of the valve when the valve is closed Value without leakage; when the valve is open, the valve body should be able to withstand 1.5 times the valve working pressure.
