A flapper valve comprising a generally rigid flap which is mounted within a flexible body coating. The hinge in the flexible body is formed by using an internal reinforcement material having a permeated structure which allows for the body material to penetrate through the reinforcement material during the valve formation. This provides for a more sturdy hinge which better resists wear.
