VAL-MATIC 503A Swing Flex Check Valve 3 Inch Flanged

Val-Matic 503A Swing-Flex check valve regulates the flow of fluids, preventing backflow and ensuring unidirectional flow. By allowing fluid to flow in one direction while preventing reverse flow, they protect pumps, pipelines and other equipment from damage caused by hydraulic shock and water hammer. It is ideal for water treatment plants, wastewater management systems, industrial processes and municipal water distribution networks.

Working Mechanism:

• Val-Matic 503A swing flex check valve controls fluid flow in pipelines by allowing flow in one direction while preventing backflow. When fluid flows in the desired direction, the valve's hinged flap swings open, permitting smooth passage.
• If there's a reversal in flow or a pressure drop, the flap swings shut, preventing backflow and maintaining flow direction.
