Y-Ball Check Valve

$522.00

SKU: CV/W645BY-E-15

The 45BY Y-Ball Check Valve is a sanitary valve designed for use in sterile processing facilities. The Y-Ball check valve prevents backflow from occurring in processing lines. When there is positive pressure the ball moves away from the inlet allowing for regular flow, however when pressure stops the ball seals the inlet. If reverse pressure occurs, the ball is securely pressed against the inlet preventing backflow. This valve features Tri-clamp connections ranging from 1-1/2" to 3". The Y-Ball Check valve can be paired with the air blow check valve, please review the sizing chart below for compatibility.
