DG5S4-04 Series Pilot-Operated Solenoid Valves

Product Overview: The DG5S4-04 Series is a high-performance, two-stage solenoid-operated directional valve utilizing a pilot stage to achieve precise control under high-pressure conditions. Centered on the Size 04 (NG10) nominal bore, this series uses an upper solenoid pilot valve to actuate the main lower spool. This design allows for smooth switching of high-flow lines while maintaining low solenoid power consumption. Its rugged cast-iron body ensures an extended service life under high-frequency operation, making it ideal for metalworking equipment, injection molding machines, and large-scale hydraulic power units.

Featured models: DG5S4-046A-T-M-U-H5-60 and DG5S4-043C-T-MUH5-60.

Key Technical Advantages:

• Superior Flow Management: Compared to direct-acting valves of the same size, the DG5S4 pilot structure significantly reduces hydraulic shock during shifting, improving system smoothness.

• Low Power Consumption Control: Requires minimal electromagnetic signals to drive the large-bore main spool, effectively reducing heat generation in electrical control systems.

• Flexible Pilot Configuration (T): Models with the “T” suffix support internal pilot supply, simplifying external piping requirements for manifold blocks.

• Wet-Pin Solenoid Technology: The armature operates within hydraulic fluid for excellent heat dissipation and lubrication, supporting a 100% Duty Cycle (ED).
