The original ball is part number 45BY-2-02-U, and the compatible replacement ball is 45BY-2-02-USP, marketed as a direct substitute that restores sealing performance without replacing the entire valve. In service, the ball seats to prevent reverse flow while allowing forward product passage, a function central to Alfa Laval’s hygienic, low-pressure-drop Y-ball check valve design used in stainless-steel piping. Buna-N material is specified for this replacement ball, and Alfa Laval literature describes the 45BY family as suitable for clean-in-place environments in dairy, beverage, and pharmaceutical processing lines. Replacement parts for the 45BY family, including 45BY-2-02-U\/Buna balls, are listed by distributors such as Springer Parts and Rodem, underscoring ongoing availability for maintenance and CIP-ready systems.\u003c\/p\u003e\u003c\/div\u003e","brand":"Alfa","offers":[{"title":"New","offer_id":51657207873838,"sku":null,"price":477.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_aae1af11-55e4-4788-b2b9-7b84c8178d33.jpg?v=1769466895","url":"https:\/\/plgautomation.com\/products\/alfa-laval-45by-2-1-2-02-u-2-1-2-check-ball-valve","provider":"PLG Automation ","version":"1.0","type":"link"}
