Abstract
There is a valve assembly including a flow control valve and a flow centralizer. The flow centralizer has a flowthrough bore. The flow centralizer is downstream of the flow control valve and the flowthrough bore narrows in a direction downstream of the flow control valve. The flow centralizer may have a three-piece design including an insert defining the flowthrough bore and an orifice body and a flange ring which hold the insert in place within the orifice body.

A valve assembly comprising:
- a flow control valve;
- and
- a flow centralizer having a flowthrough bore, the flow centralizer downstream of the flow control valve, the flowthrough bore narrowing in a direction downstream of the flow control valve.
A flow centralizer for use with a valve assembly, comprising:
- an orifice body defining a bore having a minimum diameter;
- an insert defining a flowthrough bore extending between a narrow end and wide end of the flowthrough bore, the flowthrough bore having a smaller diameter at the narrow end, the insert having an insert flange defining a maximum external diameter;
- a flange ring defining a minimum internal diameter;
- and
- wherein the minimum diameter of the bore of the orifice body and the minimum internal diameter of the flange ring are each smaller than the maximum external diameter of the insert flange so that the insert flange is held in position between the flange ring and the orifice body when the flow centralizer is in use.
