ABSTRACT:
A flow passage providing improved pressure recovery in a valve having an axially movable closure element which includes the provision of an annular diffuser flow passage from the seat port to the periphery of the closure member to reduce the fluid pressure drop across the valve when the closure member is moved a limited distance to its fully open position. The annular diffuser flow passage is provided between a pair of oppositely disposed frusto-conical surfaces respectively provided on the valve body and the closure element. The closure member may also be provided with a convexly shaped projection and the valve flow passage shaped to further reduce the pressure drop across the valve.
