Abstract: Systems and methods include providing a seal for a valve assembly. The seal includes a metallic annular body having a main body portion, a first sealing leg extending from the main body portion and that provides an axial seal with a component in the valve assembly, and a second sealing leg extending from the main body portion that provides a radial seal with another component of the valve assembly. The seal may also include a sealing ring assembly having a sealing ring support and a sealing ring that forms a radial seal in conjunction with the sealing bumps of the second sealing leg.
