DN450 Check Valve

A DN450 Check Valve, approximately equivalent to 18 inches in size, is a vital fluid control device installed in pipelines to ensure flow moves in one direction only. Also called non-return valves or backflow preventers, they safeguard industrial systems by preventing detrimental backflow. Backflow can damage pumps and compressors by reversing their impellers, leading to burnout. It also prevents undesired mixing or contamination of upstream media, making DN450 Check Valves essential for maintaining system reliability and integrity.
