Abstract
A high pressure fluid control device includes a valve body defining an inlet, an outlet, and a throat disposed between the inlet and the outlet. The valve body defines a longitudinal axis. A valve seat is disposed in the throat and includes a sloped surface. A seat support is disposed in the throat and is adjacent to the valve seat. The seat support includes a sloped surface adjacent to the sloped surface of the valve seat. A control element is disposed in the valve body and includes a stem and a seating surface. The control element is movable between an open position, in which the seating surface is spaced away from the valve seat, and a closed position, in which the seating surface engages the valve seat. The sloped surface of the seat support provides a rigid support to the valve seat to resist deformation of the valve seat.
