Abstract

A fluid regulator includes a regulator body having a fluid inlet and a fluid outlet connected by a fluid flow path with a portion of the regulator body forming a first chamber and a second chamber an orifice disposed in the fluid flow path a seat and a control element disposed within the fluid flow path and shiftable between an open position spaced away from the seat and a closed position seated against the seat with the control element arranged to respond to fluid pressure changes to control flow of a process fluid through the orifice. A first diaphragm having a radially inner portion is operatively coupled to the control element and a second diaphragm having a radially inner portion also is operatively coupled to the control element.
