PDF20 double circuit hydraulic brake valve

The dual -circuit hydraulic brake valve uses the principle of a direct three -way pressure pressure decompression valve. The braking pressure is proportional to the itinerary of the operating control component or the itinerary of the pedal, and the operating power is also proportional to the itinerary of the execution agency. The pedal valve adopts the perspective of human -machine engineering, making the operation easier and simple; the pedals are self -locking mechanisms.
