HH49X Double-Disc Butterfly Type Low-Resistance Slow-Closing Check Valve

This valve is a safety device installed in pipelines or at pump outlets to prevent reverse rotation of the pump caused by pressure differences in the pipeline when the pump stops. It features a novel structure, small size, light weight, low fluid resistance, reliable sealing, smooth opening and closing, long service life, and good energy-saving performance.

It is suitable for use in water supply and drainage, fire protection, HVAC systems, and other related pipelines or pump outlets to prevent water hammer damage to pumps and pipelines caused by medium backflow, while also providing noise reduction.
