A unitary stacked shuttle valve body assembly that may be used in a well drilling blow out preventer circuit. The assembly includes substantially similar shuttle valves that may be assembled and arranged in various configurations to accommodate the requirements and restrictions of the particular circuit in which the assembly may be used. Inlet ports and outlet ports are substantially coaxial and are assembled with central seal connectors that permit rotation of the valve bodies relative to one another. Feed passages, connector passages, and main passages are provided with plugs of different configuration to permit changing port configuration to accommodate the requirements and restrictions of the circuit in which the assembly is used.
