Cast Iron Flap Valves

WATERFRONT design and manufacture the CAST IRON Flap Valves ourselves.

Our team is ready to respond to your standard required or project-orientated designs. If requested we can also mount the flap valves for you.


All flap valves are made from high quality materials or a combination of materials.

The hinged pin is adjusted to suit the valve size in order to prevent an oval hole being formed due to higher applying forces.
