摘要：A closed-loop control valve module for closed-loop controlling a fluid flow isdescribed, which comprises an electrical valve actuator motor, wherein a valve spindlecomprising 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 theposition of the valve spindle, releases or separates off a flow channel connecting a fluidinlet and a fluid outlet. A pressure compensation channel is provided which, at least in theclosed state of the closed-loop control valve module, connects an end of the valvespindle opposite the valve actuator motor to a pressure compensation area or the fluidinlet in terms of flow.
