Abstract
Fluid flow control devices and related systems and methods may include a body or housing and a plug at least partially positioned in the body or housing to define a flow path. In a position of the plug, the plug and the body or housing may collectively define a fluid flow path.
Claims19
A method of reducing a pressure in a fluid with a fluid flow control device, the method comprising:
- positioning a plug in a housing in a first closed position to at least partially inhibit fluid flow through the fluid flow control device;
- and
- rotating the plug in the housing to a second open position to enable the fluid flow through the fluid flow control device, comprising:
- directing the fluid flow through an inlet in the fluid flow control device;
- directing the fluid flow through an aperture in the plug in a lateral direction;
- altering direction of the fluid flow with a first connecting passageway defined by the housing and extending in an axial direction;
- directing the fluid flow through another aperture in the plug in another lateral direction, wherein the aperture and the another aperture in the plug each comprise a through-hole extending completely through the plug;
- altering direction of the fluid flow with a second connecting passageway defined by the housing and extending in the axial direction, the second connecting passageway being offset from the first connecting passageway;
- and
- directing the fluid flow through an outlet in the fluid flow control device.

A method of flowing fluid through a fluid flow control device, the method comprising:
- providing the fluid through an inlet in a body of the fluid flow control device;
- rotating a plug positioned at least partially within the body of the fluid flow control device to open a fluid flow channel extending through the body from the inlet to an outlet of the body;
- flowing the fluid through at least one through-hole extending entirely through the plug defining a first portion of the fluid flow channel, the at least one through-hole extending from a first lateral side of the plug to a second opposing lateral side of the plug;
- reversing a direction of flow of the fluid through a passage defined in the body defining a second portion of the fluid flow channel adjacent to the second opposing lateral side of the plug;
- flowing the fluid through at least another through-hole extending entirely through the plug defining a third portion of the fluid flow channel in the reverse direction of the flow of the fluid, the at least another through-hole extending from the second opposing lateral side of the plug to the first lateral side of the plug;
- reversing another direction of flow of the fluid through another passage defined in the body defining a fourth portion of the fluid flow channel adjacent to the first lateral side of the plug;
- exiting the fluid through the outlet of the body;
- and
- moving the plug to at least partially block the fluid flow channel.

A method of flowing fluid through a fluid flow control device, the method comprising:
- in an open position of a plug positioned at least partially within a housing of the fluid flow device:
- aligning through-holes extending completely through the plug with connecting passageways in the housing to define a fluid pathway having three or more stages between a fluid inlet and a fluid outlet of the fluid flow device, the connecting passageways in the housing comprising at least two offset slots defined in the housing and being positioned on opposing sides of the through-holes in the plug;
- flowing the fluid through a through-hole of the through-holes in the plug and into a first connecting passageway of the connecting passageways in the housing;
- flowing the fluid through a second through-hole of the through-holes in the plug and into a second connecting passageway of the connecting passageways in the housing that is offset from the first connecting passageway;
- and
- flowing the fluid through a third through-hole of the through-holes in the plug;
- in a closed position of the plug, at least partially inhibiting fluid flow along the fluid pathway between the fluid inlet and the fluid outlet with the plug;
- and rotating the plug between the closed position and the open position.
