A Flanged Y Strainer is a mechanical device used to remove and capture solid debris (like scale, rust, sediment, and other particles) from flowing liquids in a pipeline. Its purpose is to protect downstream equipment—such as pumps, valves, meters, traps, and nozzles—from damage, clogging, or reduced efficiency caused by this debris.
The "Y" describes its shape, which resembles the letter Y, allowing for a more compact design and efficient straining area. The "Flanged" refers to its connection type: it has flanged ends that bolt directly to matching flanges in the piping system.
