DN400 Check Valve

A DN400 Check Valve, equivalent to approximately 16 inches in size, is a robust one-way valve essential for fluid systems. It allows fluid to flow in one direction while effectively preventing backflow, which could contaminate upstream media. DN400 signifies its substantial size, making it suitable for large-scale applications like sewer systems where maintaining fluid integrity is critical. These valves are cost-effective solutions, ensuring reliable operation by safeguarding against the unintended reversal of flow.
