1. A pressure regulating valve for a pressure regulating assembly for regulating a flow of a fluid from a source of the fluid to a fluid consumer, the pressure regulating valve comprising:
a passage extending along an axis between an inlet and an outlet, wherein the fluid is configured to flow in a downstream direction between the inlet and the outlet;
a seal seat positioned in the passage and defining an opening;
a seat stem positioned in the passage and moveable between a closed position in which the seat stem engages the seal seat and prevents a flow of fluid through the opening of the seal seat to prevent fluid from flowing between the inlet and outlet, and an open position in which the seat stem is spaced from the seal seat and permits a flow of the fluid through the opening of the seal seat and between the inlet and outlet;
a seat retainer positioned in the passage adjacent to the seal seat with the seal seat positioned axially between the seat retainer and the seat stem for inhibiting axial movement of the seal seat; and
a stem nut in the passage downstream of the seat retainer and axially against the seat retainer for axially holding the seat retainer in place.
