Alfa Laval 45BY-3-1 2-02-E Check Valve Buna Ball

The Alfa Laval 45BY-3-1 2-02-E is a 2-inch Tri-Clover (Tri-Clamp) Y-body ball check valve designed to prevent backflow in hygienic processing lines. It uses a Buna-N ball and matching elastomer seal to deliver a reliable seal against reverse flow while preserving cleanability in sanitary systems found in dairy, beverage, pharmaceutical, and biotech applications. End connections are Tri-Clamp clamps, enabling quick disassembly for cleaning and CIP without sacrificing sanitary integrity. As a member of the 45BY family, the valve’s compact Y-body design helps minimize flow disruption and nuisance pressure drop in forward operation, making it suitable for line protection in transfer piping, CIP loops, and pump discharge paths. The 2" size corresponds to standard Tri-Clamp piping, and the 2-02-E designation identifies this Buna-ball variant, ensuring compatibility with typical product liquids encountered in hygienic processing environments. This valve provides dependable one-way flow control in demanding sanitary systems where easy disassembly for sanitation is essential, without introducing metal seals or excessive flow resistance in the forward direction.
