The Slip On Duckbill Check Valve is installed over the end of a plain ended pipe to prevent back flow.

2 design options as follows:

- Flared model

- Flat bottom model

Choosing a Curved Bill or Straight Bill:

Curved Bill model - provides 50% more sealing area compared to the straight bill ended duckbill check valve, enabling a better tighter seal when debris are present. Does require a slightly higher cracking pressure to open the valve compared to the Straight Bill model.

- Straight Bill model - opens with minimal cracking pressure, if debris are present there is a high chance it will effect sealing performance.
