The filling valve is used for the leak-tight blocking of low-pressure systems. Due to the large flow cross-sections it is particularly suitable for fast positioning movements with low pressure, primarily on press cylinders. During the high pressure stroke the valve remains closed.
The valve consists essentially of the housing (2), valve piston (5), valve seat (6), control piston (4) and a single- stage or multi-stage electrohydraulic pilot control system (1). All components are made of stainless steel or bronze and are easy to replace. The use of proximity switches (3) allows a monitoring of the switching points of the valve piston (5).
The home position of the valve (normally open or normally closed) is determined by the variation of the magnetoperated pilot valve.
In the basic position shown here, the continuously applied control pressure – via the closing surface of the control piston (4) – presses the valve piston (4) into the seat (6). If the actuation of the pilot valve applies additional control pressure to the opening surface of the control piston, the valve piston will open due to the existing surface ratios.
