Abstract (en)

[origin: WO2016087114A1] Methods for calibrating a regulating valve (16), having a permanent magnet (20) which is moved with a regulating body (24) of the regulating valve (16), and having a contactless position sensor (14) which is arranged fixedly in a housing of the regulating valve (16) and in which a voltage is generated which is dependent on the magnetic field, acting thereon, of the permanent magnet (20), are known. In order to be able to regulate a gas flow by way of the regulating valve with relatively high accuracy and speed, it is proposed that, during the calibration, every voltage generated at the position sensor (14) by adjustment of the regulating body (24) of the regulating valve (16) is assigned a throughput of the regulating valve (16).
