DN65 Check Valve

The DN65 Check Valve, with a nominal diameter of approximately 2.5 inches, is a mechanical device used in piping systems to prevent the reverse flow of fluids. These self-actuating valves function without human intervention or external control, ensuring fluid flows in only one direction and protecting equipment from flow reversal. Available in various designs and materials, they feature an arrow on the body indicating flow direction. Commonly installed at pump outlets, they safeguard against backflow, preventing equipment damage and maintaining system efficiency.
