OVERVIEW: The Model YSF is a premium-grade stainless steel Y-strainer engineered for aggressive and sanitary process environments. Constructed from CF8M (316 stainless steel), it offers excellent corrosion resistance and is ideal for chemical, food & beverage, pharmaceutical, and seawater systems. Available in ANSI Classes 150, 300, 600, 1500, and 2500, the YSF handles pressures up to 6,000 psi in select configurations and comes in sizes ranging from ½″ to 12″. Its deep straining cavity and large screen surface ensure high debris-holding capacity and low pressure drop. The 304 or 316 stainless steel perforated screen is standard, with fine mesh options for particulate-sensitive systems. Each unit is hydrostatically tested to 1.5× design pressure, and the bolted cover allows for easy maintenance access. A blow-off port is provided for inline flushing.
