Patent ID: 8439329

Claim:
A method for operating an electropneumatic valve for driving a pneumatic actuator drive, the electropneumatic valve having at least one electropneumatic transducer and at least one pneumatic booster, which has at least one 3/3 way valve with a blocking center position for optionally connecting a connecting duct which connects to the actuator drive, to at least one of an air inflow duct and an air outflow duct, which are activated by the electropneumatic transducer as a function of an electrical actuation signal, the method comprising: measuring at least one position of the 3/3 way valve with a blocking center position; determining a correction value of at least a control voltage variable of the electrical actuation signal from the measured position based on the electrical actuation signal; adjusting the electrical actuation signal in accordance with the determined correction value; and activating, by the electropneumatic transducer, the at least one of the air inflow duct and the air outflow duct as a function of the adjusted electrical actuation signal to control the at least one pneumatic booster.
