Central box wire connection of DG03, DG05 hydraulic directional valves are specially designed for low operation noise and high working pressure. There are several grooves on spool to lead smooth flow curve and relief certain hydraulic impact. The energized solenoid(s) controlled by electric signal is to push the piston, which uses for back forward spool, actuators like cylinders is works as per the spool flow way.

Finotek DG03, DG05 hydraulic directional valve uses high quality of solenoid(s), it is for heavy duty working and wet-pin operation. There are two kinds of solenoid wire connection, individual and central wire connection type. The central connection is easily to replace the coils, isolated for electric, mostly used in molding injection machines as powerful hydraulic control.
