Abstract
In a control valve for adjusting a process medium flow of a technical process installation, a housing is provided with an interior to be traversed by a process medium. A valve seat is disposed inside the housing interior. A valve member is provided obstructing or clearing the valve seat wherein a flow cross section of the control valve can be altered according to a relative position between the valve member and the valve seat for adjusting the process medium flow to initiate a pressure change in the process medium flow between an upstream and a downstream duct section. An electrical consumer is provided. A thermoelectric element is coupled to supply electrical power to the electrical consumer. The thermoelectric element is disposed at a position in the housing interior for generating the electrical power resulting from a temperature difference that accompanies a pressure difference at a location of said position of the thermoelectric element.
