Ball Check Valve prevents the reverse flow of media, mainly in the water/wastewater industries. Media flow in the direction of arrow lifts the ball in the guide chamber to allow liquids to flow freely. Once the flow stops/reverses, the ball falls back into the groove, preventing backflow. VAHN-TECH ball check valves are available in Ductile Iron or Cast Iron and are used in applications such as General Water Supply, Fire Fighting, HVAC, District Cooling & Sewage System.
