Check valves

Check valves

Check valves , also called non-return check valves , allow a fluid (a liquid or gas) to flow in one direction but prevent it from flowing back in the opposite direction.

These valves are generally used to protect pumps and to prevent contamination occurring in piping systems.

Anti-backflow check valves are safety valves which are designed to adapt to different connection methods. Béné Inox proposes a selection of threaded check valves, wafer check valves and check valves for welding in order to meet your requirements.
