Abstract
A metallic seal for a 90° valve features a generally rectangular shape in section that defines a chamber open to internal pressure that can enlarge the chamber to enhance the sealing effect. Sealing occurs at discrete locations at portions of the seal that are preferably rounded in shape. Overlapping ends that define the entrance to the chamber also are positioned to minimize excessive deflection and resulting plastic deformation that could close off the entrance to the chamber.
