Abstract: Bi-directional seal assemblies for use with valves are described. An example apparatus for use with a fluid valve includes a closure member disposed between an inlet and an outlet of a fluid flow passageway of the fluid valve. The closure member is to slide relative to a cage or a valve body, wherein the closure member includes a seal gland and a passageway in fluid communication with the seal gland, the passageway to fluidly couple the seal gland and the fluid flow passageway of the fluid valve. The apparatus further includes a seal assembly positioned in the seal gland, the seal assembly including a first seal, a second seal opposite the first seal, and a spacer ring disposed between the first and second seals.

Abstract: Seal assemblies for use with fluid valves are described. An example seal assembly includes a first seal and a second seal opposite the first seal. The first and second seals are to sealingly engage a closure member of a valve and a sealing surface opposite the closure member. A spacer ring is disposed between the first and second seals to prevent the first and second seals from contacting each other. The spacer ring has an aperture therethrough to enable pressurized fluid to flow from a first side of the spacer ring and a second side of the spacer ring opposite the first side.

A spacer ring is disposed between the first and second seals to prevent the first and second seals from contacting each other. Additionally, the spacer ring is sized so that the spacer ring does not contact the closure member or the sealing surface.
