摘要:
A flapper valve and a method of making the same that does not require bearing assembly. More particularly, the flapper valve includes 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. Accordingly, the flapper valve with mold-in-place bearings does not require bearings to be separately assembled or installed prior to installation of the valve.
