Butt Welded Check Valves

The main advantages of the Hanno Valve high quality butt welded check valves include its excellent sealing performance, simple structure, compact size, lightweight, and low fluid resistance, making it suitable for various pipeline systems. The valve opens and closes based on the medium's pressure: when the medium flows forward, the valve disc is lifted by the fluid, allowing passage. When the flow reverses, the disc closes under its own gravity and the fluid's reverse thrust, effectively preventing backflow.
