Electrohydraulic Brake Valves

WABCO's electrohydraulic modulating brake valves have a closed center design used to modulate output pressures in proportion to the input current.


The latest technology for the world's toughest machines

WABCO offers a wide variety of electrohydraulic brake valves and accessories, each optimized for a specific full-power braking application, including retarding, hill holding, ABS, traction control and stability control.

Electrohydraulic brake valves are a full power valve for modulating output pressures up to 207 bar (3000 PSI) in proportion to the input current. In a full power brake system, these valves provide hydraulic power for normal and emergency power-off braking for electrohydraulic brake systems, anti-lock brake systems and traction control systems.
