The Check-All® Flanged & Drilled (HV) check valve is a one piece cast body valve with ASME/ANSI B16.5 Class 150 flanged ends. The HV series valve is used when higher flow rates and lower pressure drops are required. The valve is available in sizes 1 inch through 10 inches and standard materials of CF8M (cast 316 stainless) and WCB/WCC (cast carbon steel). The HV series valve is designed for use with mating ANSI class 150 flanges. Other materials are available upon request. The HV valve can also be used as a low pressure relief valve or vacuum breaker by using the desired spring settings.
