Abstract

A closed-loop control valve module for closed-loop controlling a fluid flow is described, which comprises an electrical valve actuator motor, wherein a valve spindle comprising a frustoconical sealing section is displaceable by means of the valve actuator motor along a valve spindle axis and the frustoconical sealing section, depending on the position of the valve spindle, releases or separates off a flow channel connecting a fluid inlet and a fluid outlet. A pressure compensation channel is provided which, at least in the closed state of the closed-loop control valve module, connects an end of the valve spindle opposite the valve actuator motor to a pressure compensation area or the fluid inlet in terms of flow.
