Ball check valves ensure media travels in one direction through a system. These valves use a ball to stop backward-flowing media from entering the system and contaminating the source. Media traveling through the line pushes the ball away from the valve seat to open the flow path and media traveling in the opposite direction pushes the ball up against the seat to stop backflow. During operation, the ball moves within the valve body and cleans itself as it rotates. These valves are compact and suited for high-pressure applications and viscous media. Inline ball check valves create a linear flow path for media to minimize pressure drops and ensure efficient flow. Food grade and sanitary inline ball check valves meet applicable 3-A or NSF (National Sanitation Foundation) 51 standards for use with dairy or food and beverage products.
