Power brake valves


Heavy construction, agriculture and forestry machinery and municipal vehicles, vehicles for material handling and special vehicles require braking systems with high operational safety at low operating forces.

These vehicles require servo-assisted or power brake systems to achieve the braking effect required by law. Power brake valves come in modular and compact design, and can be operated with fixed displacement pumps (open center) or variable displacement pumps (load-sensing hydraulic systems).
