Operation

When compressed by the compressor (1.01), the air flows to the pressure regulating valve (2.01) and to a test outlet (38.02).

After performing the adjustment of the pneumatic pressure, through the pressure regulating valve (2.01), the compressed air flows to the four-circuit valve (4.03), distributes the compressed air to the various pneumatic circuits of the brake system (service brake, parking brake, auxiliary circuits etc). It also ensures minimum pressure in each one of the circuits.
