An improved electrohydraulic brake valve with overpressure protection is provided. The electrohydraulic brake valve includes an integrated pressure limiting device coupled to a modulating valve and a solenoid assembly. The pressure limiting device transmits an axial force from the solenoid plunger to the valve spool up to a set limit, which corresponds to a maximum output pressure. Above this set limit, a pre-loaded spring within the pressure limiting device compresses, thereby isolating further travel of the solenoid plunger from the valve spool. The pressure limiting device mechanically limits the output pressure of the electrohydraulic brake valve to a maximum level to prevent overpressure in the brake system, adding a level of safety not previously available.
