Abstract

Provided in some embodiments is a system that includes a split gate valve including first and second gate sections coupled together and configured to move together within a cavity of the split gate valve between an open position and a closed position. The split gate valve includes a rolling actuator to reduce friction and to convert a rotational input into a linear motion to move the first and second gate sections between the open and closed positions. In other embodiments is provided a method that includes converting a rotational input into a linear motion to activate a split gate valve via a rolling actuator. The method also includes seating first and second gate sections of the split gate valve against opposite first and second seats to provide a double seal.

Claims

1. A system, comprising:

a valve assembly, comprising;

a valve body having a fluid passage that intersects with a valve cavity, wherein the valve cavity has four flat interior sides extending along an axis of the valve cavity, and an exterior of the valve body has four flat exterior sides extending along the four flat interior sides; and

a valve disposed in the valve cavity.

2. The system of claim 1, wherein the exterior has a substantially rectangular outer perimeter having the four flat exterior sides.

3. The system of claim 1, wherein the valve cavity has a substantially rectangular inner perimeter having the four flat interior sides.

4. The system of claim 1, wherein the four flat interior sides are substantially parallel with the respective four flat exterior sides.

5. The system of claim 1, wherein the valve body has a substantially uniform wall thickness between the four flat interior sides and the respective four flat exterior sides.

6. The system of claim 1, wherein the four flat exterior sides comprise first and second flat exterior sides that are opposite from one another and substantially parallel to one another.

7. The system of claim 6, wherein the four flat exterior sides comprise third and fourth flat exterior sides that are opposite from one another and generally crosswise to the first and second flat exterior sides.

8. The system of claim 7, wherein the third and fourth flat exterior sides are substantially parallel to one another.

9. The system of claim 1, wherein the four flat interior sides comprise first and second flat interior sides that are opposite from one another and substantially parallel to one another.

10. The system of claim 9, wherein the four flat interior sides comprise third and fourth flat interior sides that are opposite from one another and generally crosswise to the first and second flat interior sides.

11. The system of claim 10, wherein the third and fourth flat interior sides are substantially parallel to one another.

12. The system of claim 1, wherein the four flat exterior sides comprise first and second flat exterior sides that are opposite from one another, the four flat interior sides comprise first and second flat interior sides that are opposite from one another, the first flat exterior side is substantially parallel to the first flat interior side, and the second flat exterior side is substantially parallel to the second flat interior side.

13. The system of claim 12, wherein the four flat exterior sides comprise third and fourth flat exterior sides that are opposite from one another, the four flat interior sides comprise third and fourth flat interior sides that are opposite from one another, the third flat exterior side is substantially parallel to the third flat interior side, and the fourth flat exterior side is substantially parallel to the fourth flat interior side.

14. The system of claim 1, where the valve has four sides in contact with the respective four flat interior sides of the valve cavity.

15. The system of claim 1, wherein the valve comprises a gate valve.

16. The system of claim 15, wherein the gate valve is split into first and second valve sections.

17. The system of claim 16, comprising a biasing element between the first and second valve sections.

18. The system of claim 1, comprising a rolling actuator coupled to the valve.

19. The system of claim 1, wherein the valve assembly is coupled to a component of a mineral extraction system configured to extract petroleum or natural gas.

20. A system, comprising:

a valve body having a fluid passage that intersects with a valve cavity, wherein the valve cavity has four flat interior sides extending along an axis of the valve cavity, and an exterior of the valve body has four flat exterior sides extending along the four flat interior sides.

21. The system of claim 20, comprising a valve assembly having a valve disposed in the valve cavity.

22. The system of claim 20, wherein the exterior has a substantially rectangular outer perimeter having the four flat exterior sides, and the valve cavity has a substantially rectangular inner perimeter having the four flat interior sides.

23. The system of claim 22, wherein the substantially rectangular outer perimeter is substantially parallel with the substantially rectangular inner perimeter.

24. A method, comprising:

forming a valve body having a fluid passage that intersects with a valve cavity, wherein the valve cavity has four flat interior sides extending along an axis of the valve cavity, and an exterior of the valve body has four flat exterior sides extending along the four flat interior sides.

25. The method of claim 24, comprising installing a valve in the valve cavity, wherein the valve comprises four flat sides in contact with the respective four flat interior sides of the valve cavity.
