PDF20 Dual-Circuit Brake Valve
The dual‑circuit hydraulic brake valve adopts the principle of a direct‑acting three‑way pressure reducing valve. The brake pressure is proportional to the stroke of the operating control element or the stroke angle of the pedal, and the operating force is also proportional to the stroke of the actuator. The foot‑operated valve is designed with an ergonomic angle for easy and effortless operation. The pedal is equipped with a self‑locking mechanism.
