3. The working pressure of the resilient seated gate valve is required to be not less than 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; In the closed state, any side of the resilient seated gate valve should be able to withstand 1.1 times the working pressure of the valve without leakage; in the open state, the valve body should be able to withstand the requirements of twice the working pressure of the valve.
4. For the manufacturing standard of resilient seated gate valve, the national standard number of the basis should be stated. If it is the enterprise standard, the enterprise document should be attached to the purchase contract. This type of valve should generally be installed horizontally in the pipeline.
