AY-Ball Y-Ball Check Valve B C Application Get control with the BradfordTM Y-ball check valves. D These valves are designed to prevent reverse flow in systems moving liquid products. Working Principle E When the liquid flows into the inlet, the PTFE ball rolls up into the branch of the valve allowing full fluid flow. When the flow stops, equalizing the pressure, the ball drops F back into the seat, preventing backflow. Should reverse flow occur, the opposing pressure will cause the ball to seat firmly against the gasket preventing backflow. G H Features and Benefits � Two-piece construction for easier alignment � Polished ID and OD to 3A standards � Replace seat instead of entire valve � All metal product surfaces are CF8M (316) stainless I � PTFE ball steel construction > better heat and abrasion resistance � Air blow check valve can be added (see air blow check J > lasts longer between maintenance cycles valve for sizing) � Easy cleaning, no tools required K Technical Data, Specifications and Dimensions L M Dimensions (in) N Size A B C D E F 1�" 7.5 3.3 1.365 1.875 1.984 2.516 2" 8.5 3.9 1.865 2.335 2.516 3.047 O 2�" 10.0 4.5 2.370 2.870 3.047 3.579 3" 11.5 5.3 2.870 3.834 3.579 4.682 P Q R Valve Size Weight Ball Diameter Part Number Cap Size Clamp Size Cap Gasket (in) (lbs) (in) B45BY-R150 1� 4.9 2 2 2 1.6 S B45BY-R200 2 6.6 2� 2� 2� 2.1 B45BY-R250 2� 10.5 3 3 3 2.7 B45BY-R300 3 17.5 4 4 4 3.6 T � See Valve and Actuation catalog for more technical information. � Note: all dimensions are in inches.
