Our T316L Sanitary Stainless Y-Ball Check Valve fits ideally with the Sanitary Stainless Steel Air Blow Check Valve that we stock in our warehouses in West Columbia, South Carolina. As for the surface finish of the Sanitary Stainless Steel Y-Ball Check Valve, our valve is polished to meet a 3-A sanitary finish.

The working principle behind the Sanitary Stainless Steel Y-Ball Check Valve or Y-Body Check Valve begins as liquid enters the run of the y-ball check valve, the ball lifts up into the branch, thus allowing full flow of product. Upon recession of flow, valve pressure equalizes, then the ball returns and resides near the smallest area of the run, preventing back flow. If a reverse flow situation arises, opposing pressure of the product will place the ball against the run of the valve preventing back flow whether the valve is in a horizontal or vertical position.
