 2. When performing the sealing test, no external force should be applied to both ends of the valve, which will affect the leakage of the sealing surface. 

 3. For the visible leakage of the valve pressure test, the housing grinding and upper sealing tests are not allowed. If the test medium is a liquid, there should be no visible droplets or surface moisture. If the test medium is air or other gas, there should be no air bubble leakage.

 4. For low pressure seal testing of valve pressure test, visible leaks are not allowed to pass through the valve identification, the contact surface between the valve seat and the valve body, and there is no structural damage. Reference Standard API 598 Test Test Allowable Test Medium Leakage Rate Through Sealing Surface Duration.
