What is an Audco Swing Check Valve?

An Audco Swing Check Valve is an automatic valve that uses a hinged disc to control the direction of fluid flow. When fluid moves in the forward direction, the disc swings open, allowing unrestricted flow. If the flow reverses, the disc automatically swings back onto the valve seat, creating a tight seal that prevents backflow.

Unlike manually operated valves, swing check valves require no external power or operator intervention. Their simple yet effective design makes them ideal for applications where reliable backflow prevention is essential while maintaining minimal pressure loss.
