Abstract

A pneumatic valve for controlling a gaseous medium, the pneumatic valve including a housing including an inlet and an outlet; a primary piston that forms a primary stage in cooperation with a primary valve seat in the housing, wherein the primary piston is axially movable in a housing bore along a longitudinal axis to open and close a direct volume flow connection between the inlet and the outlet; a pilot piston that forms a pilot stage in cooperation with a pilot valve seat at or in the primary piston, wherein the pilot piston is operatively connected with an electromagnetic actuator for opening or closing a throttle bore in the primary piston, wherein the inlet is connectable with the outlet indirectly through the primary piston by the throttle bore.
