SWING CHECK VALVE

Simple & Reliable Backflow Prevention

IO Valves Swing Check Valves are designed to prevent reverse flow in water and wastewater pipeline systems. The valve operates through a hinged disc that opens with forward flow and closes automatically when flow stops or reverses, ensuring dependable non-return functionality. With a simple and robust construction, swing check valves are suitable for a wide range of general pipeline applications where reliable backflow prevention and minimal maintenance are required.
