Abstract: A valve assembly that includes a main valve having a valve member moveable between a closed position and an open position. The main valve has an upstream side and a downstream side. The valve assembly includes a pressure equalizing assembly for equalizing the fluid pressure across the main valve. The pressure equalizing assembly includes a line extending from the upstream side of the main valve to the downstream side of the main valve and a pressure equalizing valve assembly.

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.
