Abstract
A pressure regulating valve includes a housing having a valve inlet and a valve outlet. A movable piston is located in the housing, and a position of the piston is determined by a selected difference between and inlet pressure and an outlet pressure. The movable piston at least partially defines one or more flow channels between the valve inlet and the valve outlet. When the movable piston is in a fully open position, an axial inlet opening at an inlet end of the one or more flow channels is smaller than an radial depth of the one or more flow channels at the inlet end of the one or more flow channels.
