The Check-All Flanged & Drilled (HV) check valve is a one-piece cast full-bodied spring loaded check valve with ANSI/ASME B16.5 Class 150 flanged ends. The HV series spring check valve is used when higher flow rates and lower pressure drops are required. The valve is available in sizes 1 through 10 inches and standard materials of CF8M (cast 316 stainless) and WCB/WCC (cast carbon steel). This check valve is designed for use with mating ANSI class 150 flanges. Other materials are available upon request, please contact [email protected].
