The invention relates to a valve (21) for a fluid or gaseous medium, with a displaceable valve body (8), by means of which the clear flow cross-section is adjustable. The valve (21), viewed in the direction of flow, comprises a pressure sensor (1) up- or down-stream of the valve body (8), to record the pressure of the medium and the valve body (8) is controlled depending on a signal from the pressure sensor (1) and/or an external controller (2).
1. A valve for a liquid or gaseous medium comprising a movable valve body, by way of which the internal through-flow cross-section is adjustable, wherein the valve has a pressure sensor for detecting the pressure P(act) of the medium, wherein the detected pressure P(act) is passed from the pressure sensor in the form of electrical signals and is supplied to a regulating device whose regulator operates the valve body in dependence on the signal from the pressure sensor, wherein the regulating device ascertains a pressure reference value P(ref) which it pr...
