What are flap gates used for?
Flap Gates can be made of many different types of metal (Cast or Ductile Iron, Aluminum, or Stainless Steel, they are typically rated in the amount of head pressure they can withstand without damage. Flap Gates are used to stop reverse flow at the end of pipes and structures.
How does a flap valve work?
