3 For CPVC EPDM & FKM VALVES , add the letter C to part numbers listed ( , 752311-030C).General Installation InformationSpears WAFER BUTTERFLY VALVES are designed for system connections between two flanges having ANSI Class 150 bolt hole patterns. The valve handle (or gear operator) is reversible 180 for either left or right side operation. WAFER BUTTERFLY VALVES have built-in flange gaskets and are designed for installation with user supplied hex bolts, nuts and flat washers. The valve must be positioned with gasket areas evenly located between mating flange sealing surfaces. Valve Bolt Specification bolt lengths in table below are minimums based on use of two (2) Spears flanges, Valve with built-in gaskets, standard hex bolts and Standard Plate W Series flat : Spears WAFER BUTTERFLY VALVES are designed for use with flanges or flanged equipment having minimum waterway inside diameter no less than that of Schedule 80 PVC pipe (ASTM D 1785).
