Pilot Operated Directional Valve DG3V-5-10 Design Solenoid Controlled Pilot Operated Directional Valve DG5V-5-10 Design General description DG*V-5 valves are used primarily for controlling the starting, stopping and direction of fluid flow. Two series of valves, DG5V solenoid controlled, pilot operated and DG3V pilot operated models are available with a wide selection of spools. These include meterin and meter-out spools and a regeneration type that can obviate extra valves essential in traditional circuit arrangements. Features and Benefits All spools have been designed to provide good low shock,...

Note : For information on pilot valves please refer segment B of the catalog

Performance Data Pilot Pressures Differential pressure, i.e. pilot pressure at port P (or port X) minus pilot drain pressure at port T (or port Y). All main stages are spring centered. Selection of spool offset positions “a” or “b” requires pilot pressure equal to or in excess of the above minimums to move the spool against the spring force. This is particularly important when using external pilot pressure supply. Maximum 315 bar (4567 psi) Minimum (for max. flow): For spool types 0, 1, 8 , 11 4,5 bar (65 psi) For spool type 6 8 bar (116 psi)  When using a type 8 spool with the valve configured...
