DN200 Swing Check Valve for Reliable Flow Control
The DN200 swing check valve is a robust and highly efficient non-return valve, designed to prevent backflow in pipelines. Commonly used in water supply, wastewater, and industrial fluid systems, it allows fluid to flow in one direction while automatically closing to block reverse flow.
Crafted with precision and built using durable materials such as cast iron, brass, or PVC (based on application), this swing check valve is engineered for performance and longevity. It features a hinged disc that swings open with the flow and closes when flow reverses, ensuring a tight seal and minimizing pressure loss.
Easy Installation & Maintenance
Installation is simple, with flanged ends or threaded connections based on your system requirements. The valve can be installed in both vertical (upward flow only) and horizontal pipelines.
Swing Check Valve vs Spring Check Valve
Compared to spring check valves, the swing design offers lower pressure drop and less turbulence, making it ideal for large-diameter pipelines like DN200. For more dynamic applications with rapid flow reversal, spring check valves may be considered.
