Solenoid Operated Directional Valves DG4V-2 10 Design General description and application benefits These solenoid operated directional control valves are for directing and stopping flow at any point in a hydraulic system. The features being released with this range are based on Eaton experience with size 3 valves. • Efficient control of high hydraulic powers with low solenoid power consumption. • Low internal leakage reduces power losses, increases system efficiency - the result of improved manufacturing techniques for spools and bores. • High sustained machine productivity and higher...
