ABSTRACT:
A control valve assembly is disclosed for control of a fluid pressure between a variable fluid pressure source and a fluid operable device. This assembly provides a valve means to open or close flow from the fluid pressure source in response to a change in a significantly lower fluid pressure in a pilot chamber, which fluid pressure is controlled by a proportional solenoid operator requiring small current flow. This small current flow to the solenoid operator is due to the low pressure in the pilot chamber, which when relieved or increased effects a change in the valve meaans to open or close fluid flow to or from the fluid pressure source.
