摘要: The invention relates to a controller without auxiliary energy for controlling working fluid flow of a, in particular, technical process system, comprising control valve and an actuating drive which is designed actuate the so as obtain supply power providing force exclusively from and/or fluid. According invention, magnetic field source provided, coupled such that it follows movement valve, thereof being detected by sensor order determine position valve.
