Abstract:
A system, in certain embodiments, includes an annular ball valve seat including an annular spring, which biases the annular ball valve seat axially. More specifically, in certain embodiments, the annular ball valve seat includes a main body section, a lip section extending from the main body section, and a seat groove between the main body section and the lip section, wherein the first annular spring is disposed within the seat groove. A first leg of the annular spring biases the lip section in a first axial direction and a second leg of the annular spring biases the main body section in a second axial direction opposite the first axial direction. The annular ball valve seat is configured to be disposed within a ball valve, on either side of a ball of the ball valve. The particular design of the annular ball valve seat enables pressure within a body cavity of the ball valve to be self-relieving.

Claim (Index 18):
A system, comprising:\n a valve housing comprising an annular groove; a ball disposed in the valve housing; a unitary annular ball valve seat disposed within the annular groove, the unitary annular ball valve seat comprising axially opposite first and second surfaces, the first surface comprises a first angled portion and a second angled portion, the first angled portion defines a first length and the second angled portion defines a second length, wherein the second length is greater than the first length and the second angled portion is configured to contact the ball, wherein the first and second angled portions are radially offset from each other and acutely angled relative to a central axis of the unitary annular ball valve seat, wherein the radial offset is configured to block contact between the first angled portion and the ball, and wherein the unitary annular ball valve seat is configured to self-relieve; and an annular spring disposed within a seat groove of the unitary annular ball valve seat, wherein the seat groove extends radially into the unitary annular ball valve seat at a position axially between the first and second axial surfaces of the unitary annular ball valve seat, and the annular spring biases the opposite first and second axial surfaces of the unitary annular ball valve seat axially into contact with the ball and the valve housing.
