Abstract
Seal assemblies for use with fluid valves are described. An apparatus includes a cage, a plug having a seal gland and a seal assembly to be at least partially positioned in the seal gland. The seal assembly includes a back-up ring having a wedge-shaped protrusion and a seal defining a wedge-shaped groove to receive the protrusion. A pressure is to act on the back-up ring to urge the protrusion into the groove. An engagement between the protrusion and the groove is to urge the seal into sealing engagement with an inner surface of the cage.
