Abstract

The invention relates to a valve device (1) for controlling a pneumatic trailer air suspension system (100), comprising at least one cushion connection (2, 4) connectable to a pneumatic spring cushion (102a, 102b, 102c, 104a, 104b, 104c) of the air suspension system (100), a supply connection (6) connectable to a compressed air reservoir (8), and a venting connection (5) connectable to the atmosphere. The valve device (1) has a pneumatically actuable main valve unit (10), an electrical pilot control unit (12), and a manual pilot control unit (14), the electrical pilot control unit (12) and manual pilot control unit (14) are adapted for proving at least one first pilot pressure (p1) to said main valve unit (10). The main valve unit (10) is adapted to provide at least a cushion pressure (pC) at said cushion connection (2, 4) dependent on the first pilot pressure (p1). The manual pilot control unit (14) comprises a manually operatable camshaft (16) for controlling at least a first valve body (18), wherein said camshaft (16) at least is rotatable into a driving position (R1), a lowering position (R2) and a lifting position (R3). According to the invention a shaft sensor (20) for directly determining the rotational position of said camshaft (16) provided.
