ABSTRACT:
A valve for regulating a gas or liquid has a valve housing with an inlet and an outlet. A valve seat is arranged in the valve housing and connects the inlet to the outlet via a valve opening. A valve body facing the valve seat is formed by a band attached at a first fixation point and a second fixation point. The first fixation point is at one end of a lever. An actuator is arranged on the other end of the lever to act on the lever so the distance between the first fixation point and the second fixation point increases. The band is then stretched, and the valve opening is exposed, enabling gas/liquid to flow toward the outlet. When the actuator's action on the lever is regulated, an exact flow of gas/liquid can be regulated.
