What is a Y-Type Strainer?

A Y-Type Strainer is a plumbing device used to remove debris from pipelines, protecting equipment like pumps, meters, and valves from damage. The strainer has a Y-shaped body with a screen inside that traps solid particles while allowing fluid to pass through.

What are the applications of Bronze Y-Strainer?

Bronze Y-Strainer is used in water supply lines, oil pipelines, steam systems, HVAC systems, and industrial process lines. It protects pumps, compressors, meters, and other equipment from damage caused by rust, scale, and other debris.

What is mesh size and why is it important?

The mesh size refers to the number of openings per linear inch in the straining screen. A finer mesh (higher number) captures smaller particles but restricts flow more. Standard strainers use 20-40 mesh screens depending on the application and particle size to be filtered.

How often should the strainer screen be cleaned?

The cleaning frequency depends on the application and debris load. In clean water service, annual inspection is usually sufficient. In dirty or process fluid service, more frequent cleaning may be needed. The easily renewable design allows quick screen replacement without removing the strainer from the pipeline.
