All trailer vehicles Functions of the trailer brake valve and
the double release valve combined in
one unit (including emergency brake
function).
Select Low Valve
(Double cut-off valve)
434 500 003 0
Vehicles with 2S/2M+Select Low con-
trol, e.g. with steering axle.
The input pressures are the pressures
output by the trailer modulator for each
side. The lower pressure is directed to
the axle to be braked.
Select High Valve
(Double check valve/Two-way valve)
434 208 055 0
Vehicles with 4S/2M+1M system for
actuating the separate ABS relay valve.
The input pressures are the pressures
