Abstract of the Disclosure A flow control manifold assembly, constructed of a number of manifold valve assemblies. Each manifold valve assembly is formed of first and second valve bodies, each body having at least one inlet port and a plurality of outlet ports. The two valve bodies are connected together in fluid communication with each other. Associated with each valve body is an actuator assembly, which includes a valve actuator and an actu- ator rod attached to and projecting outward from the actuator, and actuatable by the actuator. In at least one of the valve bodies, a bonnet is affixed to the actuator, and projects into the respective one of the valve bodies. A valve stem, carrying at least one valve plug, is attached to the projecting end of the actuator rod, positioning the valve plug on the oppo- site side of the bonnet from the actuator. The bonnet includes a valve seat for engagement with the valve plug when the valve plug is actuated to a predeter- mined position by the actuator. One embodiment pro- vides a third valve body, also in fluid communication with the first valve body, so that flow from one source to two destinations can be controlled by a sin- gle valve assembly. Thus the invention replaces a single, expensive, multiple-actuator valves with a pair of inexpensive single-actuator valves which together are less expensive than the single valve they replace, while still preventing the mixing of different types of fluids.
