Abstract
A wafer valve assembly for securing between two flange fittings, each of the flange fittings having a flow passageway therethrough and comprising an annular flange extending radially from the flow passageway. The valve assembly comprises a valve body having a flowway therethrough and a valve element mounted in the flowway for movement between a first position closing the flowway and a second position opening the flowway. Adapter means are secured to the valve body, and alignment means cooperate between the adapter means and the flanges to place the flow passageways and the flowway in substantial register.
