ABSTRACT:
A valve, such as a butterfly valve having an offset closure vane and stub shafts for operating the vane in the flow passage of the body, has all exposed and/or potentially vulnerable metal surfaces encapsulated in a corrosion-resistant polymeric plastic coating. Providing bearing support for the vane drive shaft are a pair of spaced apart journal bearings located in the shaft bore in a shrink fit relation to the coating thereat.
