Pressure testing of low-temperature gate valves
Thread Content
Do the pressure relief holes of low-temperature gate valves and the indicated medium flow direction affect their ability to provide dual-direction sealing and withstand pressure in both directions?
Since there are indicators showing the flow direction of the medium on the valve body, it cannot be a valve with bidirectional sealing; and if there are pressure relief holes on the gate, it still cannot be a valve with bidirectional sealing.
