Non-slam check valves are check valves that stop fluid flow in the opposite direction. These valves are also designed to prevent or eliminate water hammer and its resulting impacts. These valves are tested under various parameters to ensure their high working and excellent durability. Water hammers are avoided by using non-slam check valves, which also guarantee that fluid only flows in one direction. When a pump or valve closes fast in a piping system, the fluid flow abruptly ceases, creating a high-pressure shock wave known as a water hammer.
