Swing Weight Loaded Check Valve

Weight-loaded check valves use the gravity potential of a weight to assist disc closing. They open and close automatically by medium flow to prevent backflow. The weight structure provides extra closing torque for faster, more reliable closing, effectively reducing or eliminating pump shutdown water hammer. Suitable for water supply & drainage, water conservancy, power, petrochemical and other industries.
