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.
- Available in a range of rubber materials such as Neoprene, NBR, EPDM, Viton - contact us for a quote.
- 12 months warranty on manufacturing defects only.
