Technical Datasheet -- Y-Pattern Pipeline Strainers for Particulate Filtration
Y-type strainers for pipeline filtration of particulates and debris. 45-degree screen angle provides a large filtration area with low pressure drop. Bolted cover with drain plug allows cleaning without removing the strainer from the pipeline. Perforated or mesh SS316 screen options. ASME B16.34 / MSS SP-80 compliant. Optional differential pressure taps and magnetic insert.
