Abstract: This invention relates to a pneumatic valve assembly for controlling a compressed air stream in response to a non-contacting actuation. It is desired to provide such a valve assembly which is adapted to control high working pressures without an intermediate amplifier. This is accomplished in that a pivoted one-armed or double-armed lever is provided with a permanent magnet on one side or on each of both sides of its pivotal axis and via a ferromagnetic or magnetic actuating member which is moved into the proximity of the permanent magnet or magnets and via a plunger causes a pilot orifice to be opened or closed, which orifice is adapted to be flown through by a pilot air stream for actuating a pilot piston for moving a valve piston to positions in which the valve is opened or closed.
