7. The system of claim 6 , wherein the actuator comprises a recess that is configured to receive a tool, and rotation of the tool is configured to cause rotation of the actuator and to drive the actuator along the axial axis relative to the annular energizing plug body.

8. The system of claim 1 , wherein the actuator does not overlap the wellhead component along the axial axis while the actuator drives the valve member of the first portion into the open position.

9. A flow control assembly, comprising:

an annular plug body configured to be positioned within and to be coupled to a first passageway formed in a wellhead component;

a valve member positioned within a first cavity of the annular plug body, wherein the valve member is configured to move in an axial direction relative to the annular plug body between a closed position in which the valve member forms an annular seal with the annular plug body to block fluid flow across the flow control assembly and an open position in which a gap is provided between the valve member and the annular plug body to enable fluid flow across the flow control assembly;

an annular energizing plug body configured to be positioned within and to be coupled to a second passageway formed in a body that is configured to be coupled to the wellhead component; and

an actuator positioned within a second cavity of the annular energizing plug body and threadably coupled to the annular energizing plug body, wherein rotation of the actuator causes the actuator to move toward the valve member in the axial direction relative to the annular energizing plug body to drive the valve member from the closed position to the open position, and the actuator is configured to disengage from the valve member to enable the valve member to move from the open position to the closed position when the body separates from the wellhead component.

10. The flow control assembly of claim 9 , comprising a biasing member configured to bias the valve member toward the closed position.

11. The flow control assembly of claim 9 , wherein the annular plug body is threadably coupled to the first passageway, and the annular energizing plug body is threadably coupled to the body.

12. The flow control assembly of claim 9 , wherein the actuator comprises a recess that is configured to receive a tool such that rotation of the tool causes the rotation of the actuator.

13. The flow control assembly of claim 9 , wherein the body is configured to support a valve that is configured to adjust a flow of fluid from a fluid source into the second passageway, and the flow of fluid from the fluid source is configured to drive the valve member into the open position to enable the flow of fluid from the fluid source to travel across the flow control assembly into a bore defined by the wellhead component.

14. The flow control assembly of claim 9 , wherein the flow control assembly is a valve removal plug assembly and the wellhead component is a tubing head.

15. A system, comprising:

a body configured to be coupled to a wellhead component;

a flow control assembly, comprising:

a first portion configured to be positioned within and to be coupled to a first passageway formed in the wellhead component;

a second portion positioned within and coupled to a second passageway formed in the body;

wherein a component of the second portion is configured to engage a corresponding component of the first portion to cause the flow control assembly to move from a closed position to an open position to enable a first flow of fluid to travel across the flow control assembly in a first direction from a bore of the wellhead component to the second passageway while the body is coupled to the wellhead component, the corresponding component of the first portion is configured to move in response to a second flow of fluid flowing in a second direction from the second passageway toward the bore of the wellhead component to cause the flow control assembly to move from the closed position to the open position to enable the second flow of fluid to travel across the flow control assembly in the second direction while the body is coupled to the wellhead component and while the component is disengaged from the corresponding component, and separation of the body from the wellhead component causes the component to disengage from the corresponding component to enable the flow control assembly to move to the closed position in which fluid flow across the flow control assembly is blocked.

16. The system of claim 15 , comprising a biasing member configured to bias the corresponding component of the first portion toward the closed position.

17. The system of claim 15 , wherein the component comprises a recess that is configured to receive a tool such that rotation of the tool causes rotation of the component and drives the component in an axial direction to engage the corresponding component.

18. A system, comprising:

a flow control assembly, comprising:

a first portion configured to be positioned within and to be coupled to a first passageway formed in a wellhead component; and

a second portion configured to be coupled to a second passageway formed in a body that is configured to be coupled to the wellhead component;
