Horizontal Vertical Flanged & Drilled (HV)

The Check-All Flanged & Drilled (HV) check valve is a one-piece cast body valve with ANSI/ASME 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 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, please contact sales@checkall.com.
