Abstract
A valve for regulating the flow of a medium has a valve housing with an inlet for the medium that is to be regulated, and an outlet for a regulated medium flow, a valve face with a valve opening, a movable sealing part that is arranged so that it is influenced by the medium flow in the direction of opening of the valve, and which closes and opens the valve opening as well as regulating the flow of medium through the valve opening. The valve further has an arrangement for controlling the position of the sealing part. In order to obtain a valve of this type in which a gas flow can be regulated with a high degree of precision, and can seal hermetically in a closed position using simple and inexpensive structure, a duct for the flow of the medium is arranged between the inlet and the side of the movable sealing part facing away from the valve face.
