Abstract

A diaphragm control valve includes a diaphragm valve and a valve control. The diaphragm valve includes a valve housing having a flow channel, a diaphragm, and an actuator. The valve control comprises an actuating element. The valve control comprises a correction element and provides a plurality of predefined correction characteristic lines. The valve control is arranged such that a user can select one of the correction characteristic lines, and the correction element along with the selected correction characteristic line determines a corrected position set value from a preset position set value. The actuating element is configured to determine a manipulated variable from the corrected position set value and to control the actuator using the manipulated variable such that the diaphragm control valve has a predetermined diaphragm control valve characteristic line.
