The valves that allow only one direction of flow are called check valves. The check valves are used in hydraulics mounted on the outlet pipes of the circulation pumps, and allow adjustment of the direction of flow while avoiding backflow, that is, the rising of the liquid when the tap is closed.
There are several models of check valves:
- clapet for air chambers
- with counterweight closure for pumping systems
