Zeron Fastners
Industrial Valves & FastenersBall Type Check Valves
Ball Type Check Valves (Ball Non-Return Valves) are simple, highly dependable non-clogging check valves specifically designed for viscous liquids, municipal sewage, sludge, and industrial slurries. The valve utilizes an internal rubber-encapsulated steel or phenolic ball that rolls completely out of the flow stream into a dedicated side pocket during forward flow, creating an unobstructed full-bore conduit that prevents ragging, solids accumulation, and head loss.
When pumping stops, the ball rolls back smoothly by gravity and liquid backpressure onto an inclined resilient seat, providing positive bubble-tight shutoff against backflow. Zeron Fastners manufactures Ball Check Valves in Ductile Iron, Cast Iron, and Stainless Steel (CF8M) in sizes 1.5" to 16" (DN40 - DN400) in both Flanged and Screwed end patterns.
