A single-piece flow-control assembly is configured to be disposed within a pit assembly in a manner which allows the flow-control assembly to be easily and quickly removed and replaced. The flow-control assembly includes one or more regulators rigidly connected to a mounting assembly having two coupling mechanisms adapted to rigidly mount to at least one of a fluid inlet pipe or a fluid outlet pipe at locations away from the ends of these pipes. The coupling mechanisms provide a sealed engagement between the ends of the flow-control assembly and the fluid inlet pipe and the fluid outlet pipe when the flow-control assembly is properly installed within the pit assembly. A fluid passageway with a 180 degree bend therein may be provided as part of the flow-control assembly so that the coupling mechanisms simultaneously couple to or decouple from the fluid inlet and outlet pipes by movement of the flow-control assembly in one direction.

Replaceable flow-control assembly for use in a fluid flow line

A single-piece flow-control assembly is configured to be disposed within a pit assembly in a manner which allows the flow-control assembly to be easily and quickly removed and replaced. The flow-control assembly includes one or more rigidly connected regulators disposed between two coupling mechanisms and includes a bracket that mounts the flow-control assembly at a fixed location within the pit assembly. The coupling mechanisms provide a sealed engagement between the ends of the flow-control assembly and a fluid inlet pipe and a fluid outlet pipe when the flow-control assembly is properly installed within the pit assembly. A fluid passageway with a 180 degree bend therein may be provided as part of the flow-control assembly so that the coupling mechanisms simultaneously couple to or decouple from the fluid inlet and outlet pipes by movement of the flow-control assembly in one direction.
