A flow control manifold assembly, constructed of a number of manifold valve assemblies. Each manifold valve assembly is formed of a single valve body that has two or three valve chambers. Each chamber is fitted with an inexpensive single actuator valve assembly. The valve chambers are connected together in fluid communication with each other at their lower ends. A bonnet is affixed to each actuator, and projects into its valve chamber and removably carries the valve stem which carries a valve plug. Each valve assembly is thus independently removable from the valve housing while the other two valve assemblies remain in place, thus providing a means to prevent unwanted loss or mixing of fluids in the system.
