Product type
Check valves are mechanical devices designed to prevent backflow in piping systems. They allow fluid to flow in one direction while automatically closing to stop reverse flow. Typically made from materials such as brass, stainless steel, or PVC, check valves are essential components in various plumbing and fluid handling applications. They are commonly used in water supply systems, sewage treatment, and industrial processes to maintain system integrity and efficiency.
