Abstract
An example control valve is disclosed herein and includes a valve body having a substantially axial fluid flow path extending from an upstream face surface to a downstream face surface of the valve body. A crank is disposed within the valve body, and a reciprocating valve trim, external to the valve body, is coupled to the crank and abuts the downstream face surface of the valve body.
Claims33
A control valve comprising:
- a valve body having a substantially axial fluid flow path therethrough and an upstream face surface and a downstream face surface;
- an axially slidable valve trim disposed external to the valve body within a downstream conduit;
- and
- a crank disposed within the valve body, the crank extending outside the valve body to operably couple to the axially slidable valve trim in the downstream conduit,
- wherein the axially slidable valve trim comprises a cage and a plug, the cage abutting the downstream face surface, the cage including a sidewall defining a cage bore having a cage bore axis and the cage being arranged such that fluid flowing through the valve body exits through fluid passageways in the sidewall.
2 more elements
A fluid valve control element comprising:
- a rotary closure member defining a rotational axis and being operable between a first opened position and a second closed position;
- an axially slidable fluid control member movable along a longitudinal axis and providing flow characterization of the fluid valve;
- and
- a crank operably connected between the rotary closure member and the axially slidable fluid control member, wherein rotation of the rotary closure member about the rotational axis between the first open position and the second closed position motivates the axially slidable fluid control member to travel along the longitudinal axis,
- wherein the axially slidable fluid control member includes a plurality of apertures providing a selection of inherent flow characteristics from the group consisting of:
- a linear characteristic, a quick opening characteristic and an equal percentage characteristic.

A valve assembly comprising:
- an isolation valve assembly, the isolation valve assembly consisting essentially of a valve body having a substantially axial fluid flow path extending therethrough and a rotary closure member disposed within the valve body, wherein the fluid flow path extends along a longitudinal axis;
- and
- a control valve assembly, the control valve assembly consisting essentially of an axially slidable valve trim disposed within an adjacent downstream conduit external to the valve body and being operably connected to the isolation valve assembly, wherein the axially slidable valve trim comprises a cage and a valve plug slidably disposed within the cage along the longitudinal axis.
A valve comprising:
- a valve body having a substantially cylindrical fluid flow path therethrough and including an upstream face surface, a downstream face surface, and an isolation rotary closure member disposed within the valve body being operable between a first opened position and a second closed position;
- and
- an axially slidable valve trim disposed external to the valve body within a downstream conduit and being operably connected to the isolation rotary closure member to control fluid flow through the fluid flow path,
- wherein an outlet of the valve body defines a first bore and an outlet of the downstream conduit defines a second bore such that the downstream conduit adapts the first bore to the second bore and a first diameter of the first bore is less than a second diameter of the second bore.
