Abstract
A rotatable valve assembly (20) is disclosed. In one embodiment, the rotatable valve assembly (20) includes a valve body (22) and a valve plug (24). The valve plug (24) includes a seal configured to form a fluid-tight barrier with an interior surface of the valve body. The rotatable valve assembly may include additional seals, including a seal (96) provided in the valve body (22). The rotatable valve assembly (20) further may be used with a release mechanism (40) to control the pressure at which the valve plug (24) rotates into an open position.

A rotatable pressure relief valve assembly, comprising:
- a body defining an inner surface, the plug having a central axis defining a fluid flow path;
- a plug mounted within the body, the plug being rotatable between an open position and a closed position;
- a seal attached to the plug and configured to form a fluid-tight barrier with the inner surface of the body when the plug is in the closed position;
- and,
- a shaft coupled with the plug to allow the plug to rotate between an open position and a closed position;
- wherein the inner surface of the body is curved along a cross-section along the central axis, wherein the curve is configured to accommodate the rotation of the plug;
- and,
- wherein the shaft defines a rotational axis;
- the body defines a fluid passageway having a central axis, and the wherein the rotational axis of the shaft is offset from the central axis of the fluid passageway.
A rotatable pressure relief valve assembly, comprising:
- a body defining an inner surface, the plug having a central axis defining a fluid flow path;
- a plug mounted within the body, the plug being rotatable between an open position and a closed position;
- a seal attached to the plug and configured to form a fluid-tight barrier with the inner surface of the body when the plug is in the closed position;
- and,
- a release mechanism configured to keep the plug in the closed position until a predetermined fluid pressure differential is applied to the plug;
- wherein the inner surface of the body is curved along a cross-section along the central axis, wherein the curve is configured to accommodate the rotation of the plug.
