摘要：
A high temperature servo valve to control a valve actuator for a valve body in a valve passage includes a plurality of high temperature wires to deliver a voltage; an actuator block of piezo ceramic material connected to the plurality of high temperature wires to move when it receives the voltage; a pressure supply line connecting the servo valve to the valve passage to supply air to the servo valve; a pressure vent line to vent pressure from the servo valve; and a pressure servo line connecting to the valve actuator to control the pressure in the valve actuator.
