main ebs modulator valve. genuine product. brand new. this valve is suitable fort the 6x4 or 6x2 configurations.
function of this valve:
the axle modulator controls the brake cylinder pressure
on the two sides of a single or dual axle. it has two
pneumatically independent pressure control channels with an air admission and bleeder valve each, individual pressure sensors and a joint electronic control unit. desired pressure definition and external surveillance take place via the central module. moreover, wheel rotation speed is measured and
evaluated via two speed sensors. in case of wheel-lock
or wheel-spin, the set nominal value is modified.
provision has been made for the connection of two sensors to detect brake lining wear.the axle modulator for the driving axle has an additional
connection for a redundant pneumatic braking circuit. a two-way check valve on each side drives the higher pressure (electro-pneumatic or redundant) through to the brake cylinder.
