I'm trying to design a somewhat complex small system, in which based on the configuration of certain other valves, water could be flowing along a pipe in either direction.
To be clear, given any particular configuration of the other valves the flow direction should be entirely fixed.
But different configurations could lead to that fixed flow being one way, or the other.
Given the complexity of this design, it would be nice to be able to put in something that ensured that the water was flowing in the expected direction. So …
Do there exist valves which are mono-directional, but where I can (by e.g. turning a handle) change the direction of allowed travel?

Evidently. One of several rsults of searching for reversible check valve. Image from flow-rite.com, no affiliation, never heard of them
However, I'd suggest re-examining the entire design. When complexity leads to wanting more complexity, it's more often an overly complex design ethos than a need for complex parts.
