Zusammenfassung:	The disclosure relates to a method and device for operating an electropneumatic valve for driving a pneumatic actuator drive to activate fittings in automation systems. The valve has at least one electropneumatic transducer and a pneumatic booster. The pneumatic booster has at least one 3/3 way valve with a blocking center position for optionally connecting an air inflow duct or an air outflow duct to a connecting duct, which connects to the actuator drive. The ducts are activated as a function of an electrical actuation signal by the electropneumatic transducer. At least one position of the 3/3 way valve with a blocking center position is measured and a correction value of a variable of the actuation signal is determined based on the measured value and the electrical actuation signal.
