Axial check valves are specifically designed to minimize hydraulic shock, which can occur when flow is suddenly stopped. They open in the direction of flow and close quickly and quietly once the pressure drops, avoiding the characteristic “slam” associated with conventional check valves. This greatly increases equipment longevity and reduces system noise.
These valves are primarily used in demanding applications such as pumping stations, oil pipelines, hydropower plants, and process piping with sensitive equipment.
