Valve component with connections for at least two different pressure media

The valve assembly (1) has a valve housing (2) that is provided with two housing halves (3,4) which divide the valve assembly into a pneumatic portion (5) and a hydraulic portion (6). The pneumatic portion is formed as a control chamber and the hydraulic portion is formed as a working chamber. A valve used as a slider (24) is arranged in the hydraulic portion. A compressed air connection (10) acting on a compressed air control piston (12) arranged by pneumatic portion is operable. A hydraulic input terminal (7) is connected with a hydraulic output terminal (8) by actuating slider.
