Pressure Control Element (DWB)
A change in pressure of the medium via the active bellow surface results in a change of displacement which is used as a constant control or switching function in connection with electronic or electromechanical components.
As for TÜV type series, the second, integrated control component is activated and used as a safety feature in cases where the element has become leaky.
