“Y” Strainers take their name from their configuration. They are most commonly used in
pressurized lines, gas or liquid, but can also be used in suction or vacuum conditions. 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.
