Electro-hydraulic brake valve

(1) electro-hydraulic valve, (2) valve operation selection lever, (3) release button, (4) electric

coil, (A) "NO LOAD" position, (B) "HALF LOAD" position, (C) "FULL

LOAD" position

Valve used in the system is equipped with release button (3) causing the brakes to be

applied when trailer is disconnected from the tractor. Brakes are applied as a result of

reduction of pressure in the trailer's braking system. The brakes can operate normally after

connecting the connection lead (6) and hydraulic supply conduit to tractor and after

energizing the control valve.
