Abstract
A solenoid operated valve has a pressure transducer sensing valve outlet pressure integrally formed in the valve body, such as by overmolding. Upon connection of the transducer and solenoid to an electronic controller, the controller generates a valve energization signal in response to a desired valve pressure output and the transducer input for providing closed loop control of the valve outlet pressure. An ASIC may also be integrally formed in the valve body, such as by overmolding for providing integrated signal conditioning; and, the optional ASIC, if employed, may also include the circuitry for the electronic controller for providing a 'smart' pressure control valve.
