Swing Type Check Valves
The Swing Type Check Valve is designed to prevent reverse flow in piping systems, ensuring the protection of pumps, compressors, and other equipment from potential damage. Featuring a swing-type disc, the valve opens with forward flow and closes automatically when reverse flow occurs, providing reliable and efficient backflow prevention.
