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.
