Abstract
A valve includes a valve body, a valve seat, and a poppet assembled with the valve body. The poppet includes an axially extending poppet stem and a radially extending poppet sealing surface. The poppet is axially movable between a closed position and an open position. The poppet sealing surface is defined by a sealing member disposed on the poppet stem. The sealing member is laterally movable on the poppet stem. When the poppet is moved from the open position to the closed position, the sealing member is laterally moved to align the sealing surface with the seating surface.
