Duckbill Check Valve

The Backflow Preventer device operates autonomously without needing external power or manual assistance. Unlike some check valves that rely on flow rate or pressure differentials, it operates solely based on the opening pressure required to activate it.

While certain check valve designs are susceptible to corrosion, scaling, and erosion, the Duckbill type is crafted from durable elastomeric materials. Consisting of a single-piece, flexible sleeve with a duckbill shape, it opens at a specific pressure threshold and closes below it, effectively sealing against reverse pressure and preventing backflow.

These devices can be easily installed in existing pipelines or integrated into new infrastructure, often replacing inadequate valves. Thanks to their straightforward design and sturdy build, they necessitate no maintenance and boast a lengthy service life.
