ABSTRACT:
A flapper valve assembly and a method of making the same. The flapper valve assembly is mountable to a manifold as a unit. The flapper valve assembly can include bearings that do not require assembly on a shaft of the flapper valve. More particularly, the flapper valve can include a shaft having one or more flap portions and one or more bearing portions molded in place on the shaft as a unitary structure. The bearing portions are separated from adjacent flap portions and/or the shaft thereby forming a bearing that rotates independently of flap portions on the shaft. The flapper valve is mounted to a flapper valve carrier that can include sealing members for facilitating a tight seal between the flapper valve and the carrier and/or the carrier and a manifold.
