Abstract
A control valve is fluidly coupled to chambers containing fluid of different pressures for regulating flow therebetween. The control valve has a valve housing having a chamber fluidly coupled to a first chamber, a second chamber, and a third chamber. A fluid flow regulation member is disposed in the chamber and is configured to regulate fluid flow between the second chamber and the third chamber. A diaphragm is disposed substantially perpendicular to a longitudinal axis of the chamber in which longitudinal deflection of diaphragm is representative of the pressure in the first chamber.
