Y-type strainers are most commonly used in pressurized lines, gas or liquid, but can also be used in suction or vacuum conditions. The compact and lightweight design, and the quick and easy cleaning ability, the Y-filter found in many areas of their deployment. They are intended for applications where small amounts of solid particulate are expected, and where clean-out will be infrequent. If solids will flush easily from the screen, and fluid can be exhausted to atmosphere, a blow-down valve on the drain port will allow clean-out without removal of the screen, and without interrupting the process flow.
