Functionally a valve regulates the flow of a fluid in a given duct. Such a
definition would match the gates this topic is about
https://en.wikipedia.org/wiki/Valve

A piping gate valve involves a sluice which moves in and out the full flow
section
https://en.wikipedia.org/wiki/Gate_valve

Usually, a valve can't be overflowed as it's often about pressurised piping.
In case of openflow canals water may flood surroundings, but IMHO big gates
can still be called a valve according to definition.
Wikipedia states that "Valves have many uses, including controlling water
for irrigation <https://en.wikipedia.org/wiki/Irrigation>" then imply valve
terminology would be suitable for canals.

In French valve is translated in "vanne" and refers to both kind of devices
(piping and water ways)

All the best

François
