Can a pipe equipped with a flow control valve allow flow in both forward and reverse directions?
Thread Content
I’m a student with no practical experience; I’d like to ask everyone – if a pipe originally allows flow from A to B, but at some point starts allowing flow from B to A, can a pipe equipped with a flow control valve enable such two-way flow? {:3_59:}
The valve should not present any problems, but there are issues with flow measurement; generally, flow meters have direction requirements.
Generally, both control valves and flow meters have requirements regarding the direction of flow. If it is necessary to allow flow in both directions, then one should look for control valves and flow meters that do not have such direction requirements for installation.
When designing and selecting control valves, the flow direction is already fixed; reverse flow causes little to no damage to the internal components, but it may affect the control performance
If the pressure difference isn’t significant, there should be no problem. If the pressure difference is large, it is necessary to check whether the unbalanced force meets the requirements; otherwise, the control valve cannot function properly.
One is not sufficient; the basic principle of a flow meter is the Venturi principle, and if the flow direction is reversed, the measurement results will definitely be incorrect

Okay, are there two-way flow meters in reality?
