Electro-hydraulic pilot-operated proportional throttle valve

摘要

The proportional throttle valve is electro-hydraulically piloted. For this purpose, the throttle piston (5) is connected to a differential piston (7) which is hydraulically actuated by the magnetically operated pilot valve (3). A preferably mechanical feedback (1) of the position of the throttle piston (5) on the pilot piston (3) is provided.
