Electro-hydraulic pilot control
FUNCTI
ON
HYDAC 4/2 und 4/3 directional valves for oil hydraulic
systems are to open and close flow paths. In de-energized
mode the main piston will be retained by a spring in the initial
position. An under oil switching magnet pushes the pilot piston
in its end position whereby the main piston – hydraulically
operated – moves to his end position.
Hereby the chosen flow paths will be enabled according to the
symbol of the valve. After switching-off the solenoid the pilot
piston will be pushed back in its initial position by the spring. A
manual override allow the switching of the pilot valve without
erection of the solenoid.
