Wye ("Y") Strainers can be used in horizontal or vertical (downward) pipelines. A cylindrical perforated or mesh-lined screen within the wye strainer collects debris as the flow travels through the strainer. Cleaning Y-strainers normally requires the removal of the screen from the strainer, but a blow-off drain valve can be used to increase the time between cleanings.
Features of these stainless steel inline strainers include large straining capacities, precision machined seats, a standard blow-off drain connection furnished with a plug on low pressure models, and many screen options. All cast iron and carbon steel units are epoxy painted to resist rust; all threaded and socket weld end connections have hex ends for easy installation. Many models of wye strainers have gauge taps as a standard feature.
