Spirax Sarco Fig 16L Austenitic Stainless Steel Y-Type Strainer – 316L SS for Steam & Process Lines
Spirax Sarco Fig 16L 316L stainless steel Y-strainer for steam, condensate & food-grade applications. Sizes 3/8" to 2". Buy from PC Engineering India.
Overview
The Spirax Sarco Fig 16L is a screwed Y-type strainer manufactured from austenitic stainless steel (ASTM A351 Gr. CF3M / 316L). Designed for steam, condensate, and general process applications, this strainer protects downstream equipment such as control valves, steam traps, and pumps from pipeline debris.
The standard configuration includes a 316L stainless steel screen with 0.8 mm perforations. Optional screen configurations—including finer mesh sizes (40, 100, 200) and monel screens—are available for specific filtration requirements. The strainer cap can be drilled and tapped to accommodate blowdown or drain valves.
The Fig 16L Food+ variant is certified for food-contact applications, complying with EU Regulation (EC) 1935/2004, (EU) 10/2011, and FDA 21 CFR standards—making it suitable for hygienic steam and condensate systems in food and beverage processing.
