US Patent 10197168 Energized spring seal for a floating valve seat

The technology of the present application provides a floating ball valve. The ball valve includes a valve body having a recess or chamber and a ball contained in the recess. A valve seat forms a sealing relationship between the ball and the fluid conduit. The valve seat has a resilient seat or member formed on the valve seat that confronts a surface of the ball. An energized spring seal on the opposite side forms a seal between the valve body and the valve seat and pushes the resilient seat towards the ball.
