Pneumatic valve device including a quick release insert

A pneumatic ABS valve device (10) for a pneumatic brake system (8) of a vehicle (100), the pneumatic ABS valve device (10) comprising:

• a casing (1) configured for fluid connection to a pneumatic brake, the casing (1) comprising:
• a supply port (2) for receiving pressurized air;
• a working port (3) for providing a braking pressure to a brake actuator (9);
• an exhaust port (4) for a releasing pressurized air from the brake actuator (9);
• and
• a flow path (17) defined in the casing (1) and connecting the working port (3) and the supply port (2);
• a quick release insert (5) being reversibly deformable and at least partly arranged in the flow path (17),
• wherein the quick release insert (5) is moveably received in the casing (1) and moves into a blocking position (B) when an exhaust air flow (f2) is provided by the working port (3),
• wherein the quick release insert (5) is deformed in the blocking position (B) and sealingly rests against a sealing surface (28) of the casing (1) thereby blocking the flow path (17), and
• wherein the quick release insert (5) returns into an undeformed basic position (A) in an unloaded or low-loaded condition.
