1. A centerbody assembly for a pressure regulator, comprising:
a centerbody having:
a process surface,
at least one outlet orifice disposed in the centerbody;
an outlet port positioned in fluid communication with the at least one outlet orifice;
an inlet port;
a valve chamber positioned in the centerbody in fluid communication with the inlet port, the valve chamber including a valve seat positioned in fluid communication with the process surface;
a transition conduit extending between the valve seat and the process surface; and
at least one damping port extending from the transition conduit to the process surface, wherein a longitudinal axis of the at least one damping port is disposed at an acute angle to the process surface;
a spherical valve element disposed in the valve chamber and moveable between an open position in which it is spaced away from the valve seat, and a closed position in which it seals against the valve seat;
a flexible control diaphragm facing the process surface, wherein a perimeter of the control diaphragm is bonded to the centerbody so as to define a seal that blocks the passage of fluid; and
wherein the valve element is mechanically interconnected with the control diaphragm.
