DEN DURCHFLUSS EINES DRUCKMEDIUMS STEUERNDES UMSCHALTVENTIL.

摘要

The valve seats and the valve stem of the changeover valve have different diameters from one another so that the pressure medium applied a drive force to actuate the valve. The control system is a simple and purely passive retention system without external drive, the retention being triggered by a pulse-like electric signal. The signal energy produced and transmitted within electronic control systems suffices to actuate the valve, no additional drives being necessary for such actuation.
