Abstract
An example apparatus includes a disc-shaped valve plug having a first metallic sealing surface extending circumferentially about a peripheral edge of the valve plug. The first metallic sealing surface has a first curved profile. The example apparatus further includes a valve seat defining an orifice and having a second metallic sealing surface having a second curved profile that is complementary to the first curved profile so that the first and second metallic sealing surfaces form a metal-to-metal seal when the first and second metallic sealing surfaces are in contact.
