2-1/2 Inch Check Valve

The 2-1/2 Inch Check Valve, corresponding to DN65, is crucial in fluid systems for ensuring unidirectional flow. As a Non Return Valve or One Way Valve, it protects mechanical equipment in piping by permitting fluid passage in one direction, automatically opening with forward flow and tightly sealing against reverse flow. Operating autonomously, these valves do not require manual intervention or external controls like handles or stems. By maintaining flow direction, they safeguard system integrity, prevent damage from backflow, and ensure smooth operational efficiency.
