Abstract
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.
Claims8
A manifold assembly, comprising:
- a plurality of manifold valve assemblies each including three single actuator valves, each having at least one inlet port and one outlet port;
- each of said valves including a valve actuator, an actuator rod attached to and actuatable by said actuator, one end of said rod projecting outward from said actuator, and at least one valve plug attached to the projecting end of said actuator rod;
- means for connecting an inlet port of a first one of the valves in each of said manifold valve assemblies to a supply source and an outlet port of said valve to an inlet port of a second one of said valves;
- means for connecting an outlet port of said second valve to an inlet port of a third one of said valves;
- and
- means for connecting an outlet port of said third valve to a delivery outlet.
