Check valves are designed to allow fluid to flow in one direction and automatically prevent backflow, ensuring system safety and efficiency. They operate without manual intervention, using a disc, flap, or ball to block reverse flow when the medium changes direction. Constructed from materials such as stainless steel, cast iron, brass, or carbon steel, check valves handle a wide range of pressures, temperatures, and media types. Common types include swing, lift, ball, and wafer check valves, suitable for water, oil, gas, steam, and chemical applications. Their reliable operation reduces maintenance, prevents damage, and enhances process efficiency.
