1. • • Composed primarily of elastomeric materials such as rubber or silicone, the valve features a tapered bill-like structure with a thin slit or orifice at one end. This unique configuration enables fluid flow in one direction while obstructing reverse flow, akin to the behaviour of a duck's bill when feeding.

   How does a duckbill check valve work?

   • This process occurs seamlessly without external intervention, making duckbill check valves inherently passive and low-maintenance components. As the fluid flow subsides or attempts to reverse, the elasticity of the valve material ensures that the slit reverts to its closed position, effectively sealing off the passage.

   What size duckbill check valve does red valve own?

   • Red Valve owns mandrels from 1/2-96". This allows us to build full-sized duckbill check valves every time. Other valve manufacturers construct undersized duckbill check valves due to limited tooling. They will then pass the smaller duckbill check valve of as a larger sized valve by simply providing a reducing cuf adapter.
