Description
The DB-4 inline duckbill check valve is an insertable rubber non-return valve that fits inside your pipe to stop backflow, in sizes from 100mm to 600mm ID. It is secured by an internal expanding clamp, and additional bolts can be fitted through the pre-existing holes in the clamp (drilling required). It suits low back-pressure applications. Please advise the pipe internal diameter (ID) when requesting a quote or ordering. Curved Bill or Straight Bill: the curved-bill model provides around 50% more sealing area than a straight-bill duckbill check valve, giving a tighter seal when debris is present. It cracks open from about 25cm of head pressure; the valve needs full flow with zero back pressure to open fully, and requires a slightly higher cracking pressure than the straight-bill model. The straight-bill model cracks open with minimal pressure, though debris can affect its sealing performance. Available in a range of rubber materials including Neoprene, NBR, EPDM and Viton, contact us for a quote. 12 months warranty on manufacturing defects only.
