(NON SLAM) AXIAL CHECK VALVES
Non Slam Axial Check Valves are an advanced type of check valves engineered to prevent the damaging effects of reverse flow and water hammer, while ensuring efficient flow characteristics. This type of check valves are typically used in critical industrial applications where reliable prevention of backflow and smooth, non-disruptive operation are required. At Merwede Valves we have a simple, in-line design, which responds quickly to changes in velocity.
