Pneumatic valves control the compressed air that works the brakes, the gearbox and the auxiliary circuits of a truck or trailer. Each type has one job: to let air through in one direction only, to hold a set pressure, to release a circuit quickly, to drain condensate, or to switch a line from one path to another. This section gathers every valve type Büyükdemir manufactures, grouped by function so a valve can be found either by what it does or by the OE number it replaces.
Valves is grouped into 25 sub-categories:
