DN700 Check Valve

A DN700 Check Valve refers to a check valve with a nominal diameter (DN) of 700 millimeters, roughly equivalent to 28 inches. These valves are designed to prevent backflow in large diameter pipelines. The DN700 size indicates its capability to accommodate large volumes of fluid while effectively closing to prevent reverse flow, ensuring the integrity and safety of the piping system. Such valves are crucial in industrial and municipal applications where large-scale fluid control and prevention of backflow are paramount.
