Description Check Valve is a one-way flow control valve designed to allow fluid to move in a single direction and automatically prevent reverse flow. This check valve protects pumps, pipelines, and equipment from backflow damage while maintaining system efficiency. Constructed from durable brass, cast iron, or ductile iron depending on application, the check valve provides reliable sealing, corrosion resistance, and long service life. It is widely used in plumbing, HVAC, fire protection, and industrial piping systems.
