Abstract

A centerbody assembly for a pressure regulator includes: 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 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.
