DN80 Check Valve

The DN80 Check Valve, with a nominal diameter of approximately 3 inches, is a simple yet effective one-way valve designed to allow fluid flow in a single direction. This automatic valve opens when the inlet pressure exceeds the outlet pressure, preventing backflow that can contaminate upstream media or damage equipment. They come in various designs, and materials suitable for diverse applications. Some models include vents for use as three-way check valves, further protecting the incoming water supply from contamination.
