Actuator and Control Electronics Pilot Pressure Input Pressure Output Pressure The Type-950XP utilizes a nozzle to control a pilot pressure to an integral volume booster. The resultant output pressure is measured by a pressure sensor, which in turn provides a feedback signal to the control circuitry. The feedback circuit compares this signal to the input signal and self corrects as necessary, thus minimizing the effects of vibration, position, temperature and supply pressure. The current signal flows to the piezo actuator causing it to bend toward the nozzle. This restricts the flow of air through the nozzle and creates back pressure in the pilot pressure chamber. This back pressure acts as a signal pressure which in turn controls the pressure at the output.
