One-way valve leaking in reverse direction
Thread Content
The one-way valve on the gas line is leaking in the opposite direction. This is too embarrassing. The flow meter is flooded. What should I do? What are the considerations when choosing a one-way valve?
This one-way valve is also terrible. But it's acceptable. Generally, one-way valves have metal seats. There is also a certain amount of leakage after closing. The selection of valves mainly depends on the conditions of the medium, including temperature, pressure, viscosity, density, etc. If the temperature is not high, you can choose a soft valve seat, which will reduce leakage.
