Vickers DG4V Solenoid Valves

Any Vickers DG4V Solenoid Valves, if held shifted under pressure for long periods, may stick and not spring return, due to silting. Therefore, it is recommended that the Vickers Directional Valves be cycled periodically to prevent this from occurring. Only DC coil voltages are available. For applications where the junction box is required, valves with F (flying lead) type coils must be driven by a DC electrical signal.
1. Efficient control of greater hydraulic powers without increasing solenoid power consumption.
2. Installed cost and space savings from higher power/weight-and-size ratios.
3. Increases system efficiency; the result of improved manufacture of spools and bores.
4. Installation flexibility resulting from choice of numerous combinations of solenoid connectors and        locations.
5. Multi-fluid capability without need to change seals.
6. Higher sustained machine productivity and higher uptime because of proven fatigue life and endurance,    tested over.
7. Solenoid coils can be changed quickly and easily without leakage from hydraulic system.
8. Compact, cost effective system design when used with Vickers System Stak valves and subplates.
