ABSTRACT:
A pilot operated flow regulating valve which can be remotely controlled by varying the energization to a solenoid. The valve consists of a normally-closed, spring-biased, pressure-differential-actuated, main valve element and a pressure-compensated, pilot flow valve employing a solenoid acting like a remotely controllable electromagnetic spring to control the flow of fluid through the pilot valve and the pressure difference across the main valve element.
