A DN450 Check Valve is intended for pipelines with a nominal diameter of 450 millimeters (about 18 inches). It employs a swinging disc to permit flow in one direction only. This valve is essential for preventing backflow and maintaining one-way fluid flow in substantial pipelines, such as those in sewage treatment plants and industrial facilities.
