Inline spring-loaded swing check valves ensure media travels through a system in the intended direction and prevent backflow. The spring-loaded swinging disc helps securely close the valve in the presence of low-flowing media. These valves have inline inlet and outlet ports that create a linear media flow path to minimize pressure drops and ensure efficient flow. Flowing media on the inlet side swing the disc away from the seat, opening the valve. When inlet pressure drops below outlet pressure, the disc will swing closed to prevent backflow and contamination. These valves are used in various industrial applications, such as wastewater treatment facilities.
