Industrial 1600FE-CS-SS-STL Wafer Check Valve

Sure Flow 1600FE-CS-SS-STL Wafer Check Valve is a 16-inch, ANSI/ASME Class 150 wafer-style backflow preventer from Sure Flow Equipment, designed to stop reverse flow in piping systems without a full flanged housing. It is part of Sure Flow’s FE-series retainerless wafer check valves and uses a dual-disk design that closes to prevent reverse pressure and potential water hammer in pipelines. The FE-series valves are offered in steel configurations, including cast steel (CS) and cast stainless steel (SS), with sizes ranging from 2 inches to 72 inches and flange ratings spanning ANSI Class 125 to 250, making the 16-inch Class 150 version suitable for installation between standard flanges in a wafer arrangement. The retainerless, dual-plate construction helps minimize internal crevices and simplifies maintenance, while the design aligns with API 594 wafer check valve standards for reliable non-return protection in offshore or onshore pipeline service. This model designation reflects its steel variants in the Sure Flow family, enabling selection based on service requirements and corrosion resistance, and it is well-suited for pipeline applications where space and weight are considerations compared with traditional full-flanged valves.
