Y-Strainers use a perforated or wire mesh straining element to mechanically remove unwanted solids from liquid, gas or steam lines. The most common use of a Y-Strainer is pipelines to protect pumps, meters, control valves, steam traps, regulators and other process equipment.

When the amount of material to be removed from the flow is small, Y-Strainers are very cost effective straining solutions, particularly when there are long intervals between screen cleanings. When there is more material to be removed or a “dirtier” flow a Y-Strainers can be fitted with a “blow-off” connection that permits easy cleaning of the screen without the need to remove it from the strainer body.
