A valve housing has three ports with butterfly valves mounted in two of the ports with stems coupled to the valve disks and extending through opposite sides of the housing. A linkage couples the valve stems together at one side of the housing, while an actuator is coupled to at least one of the valve stems on the opposite side of the housing. The linkage and control mechanism can be reversed such that valves can be mounted in an installation either as a left hand or a right hand valve.
