Operation:
The distribution valve (18.05) has the function of activating the semi-trailer brake upon control signals. These control signals come from the following valves: service brake valve (13.02) and parking brake valve (14.02).
The two-way valve (bidirectional) (28.01) is controlled by two different pressures and enables only one of them to get to the distribution valve. One of the pressures comes from the connector (21) of the brake pedal valve (13.02) and the other comes from the outlet (2) of the semi-trailer manual valve (15.01) .
The coupling mouths (35.02, 35.03 and 35.08) have the function of rapid and efficient engagement of the towing vehicle with the semi-trailer.
