Rubber duckbill check valves are an exceptionally reliable and cost effective alternative to flap-gate valves and other conventional check valves. Their simple one-piece design and reinforced rubber construction eliminate the mechanical and metal components that rust and seize in conventional flap-gates and check valves.

The Fuller duckbill valves we supply are passive-reactive devices requiring no external mechanisms or power source to operate. The flexible rubber sleeve is normally closed but will react and open with as little as 1 inch of head pressure and always provide maximum flow with minimal pressure drop across the valve.

Features of duckbill valves :
  • Quiet operation
  • Non slamming
  • Minimal maintenance
  • Seals around trapped objects
  • Low head loss
  • Reliable performance
