The Check Valve is a crucial component in fire protection and piping systems, designed to allow fluid flow in one direction only. By preventing backflow, it protects pumps, sprinkler systems, and water supplies from contamination or damage. These valves operate automatically and are commonly installed in risers, main supply lines, or between system zones. Available in grooved, flanged, and threaded types, made from durable brass, cast iron, or ductile iron to ensure longevity in high-pressure environments.
