Abstract: An electrically operated fluid control valve provides a controlled output pressure proportional to an electrical control signal. The valve housing has a pressure control chamber, an inlet passageway leading from an inlet port to the chamber, an outlet port connected to the chamber, and an outlet passageway leading from the chamber to an exhaust port. A supply diaphragm coupled with a supply valve at the inlet port regulates fluid pressure supplied to the chamber through the inlet passageway and another passageway communicates fluid pressure from the chamber to the supply diaphragm. An exhaust diaphragm at one end of the chamber coupled with an exhaust valve at the exhaust port regulates fluid pressure supplied to the exhaust port and the outlet passageway communicates fluid pressure between the chamber and the exhaust diaphragm.
