I. Core Features

1. Standard Compact Design: Optimized thickness and standardized structure, minimizing installation space while meeting the requirements of medium and large flow systems.
2. Pipeline-Free Connection: Stacked installation reduces oil leakage, vibration and noise issues, simplifies system construction, and improves overall reliability.
3. High Integration: Various functional modules can be freely combined, allowing quick construction of complex hydraulic circuits with flexible configuration options.
4. Easy Maintenance: The modular structure facilitates quick inspection, maintenance and replacement of individual valve components, reducing downtime.
5. Wet Solenoid: Used in solenoid directional valves (such as DSG-01) to achieve high durability, low noise and stable operation under long-term working conditions.
6. High Pressure and Large Flow Performance: Maximum working pressure up to 35 MPa (350 Bar, 5076 PSI), maximum flow rate 60 L/min (15.85 U.S.GPM) (varies slightly by valve type).

3. Automated Production Lines: Direction, speed and pressure control of executive components in large-scale automated production lines.
4. Metallurgical & Steel Mill Equipment: Hydraulic systems operating under high temperature and high pressure conditions in steel mills and metallurgical plants.
5. Heavy Construction Machinery: Hydraulic systems of medium and large construction machinery, meeting high pressure and large flow requirements.
6. Ship Equipment: Hydraulic systems for ships, with reliable performance under harsh working environments.

V. Installation and Maintenance Points

1. Before Installation:
2. Clean hydraulic oil and pipelines to prevent impurities from entering the valve body, which may cause component wear or blockage.
3. Check the condition of seals to ensure no damage; use special fluorine rubber seals when using phosphate ester hydraulic fluid.
4. Confirm that the mounting surface is flat, free of scratches or burrs, and the O-ring on the mounting surface is intact.
5. During Installation:
6. Stack valves in the order of the hydraulic principle diagram, paying attention to the direction of oil ports and ensuring correct alignment of each valve.
7. Tighten bolts evenly with the specified torque (5~6 Nm) to avoid valve body deformation or oil leakage.
8. For solenoid directional valves, pay attention to electrical connections and solenoid direction, and ensure compatibility with the system voltage.
9. Maintenance:
10. Regularly check system pressure and flow rate to ensure normal operation; the maximum number of stacked valves (including solenoid directional valves) is 5 layers when working pressure is higher than 25 MPa.
11. When adjusting pressure, first loosen the lock nut, rotate the adjusting bolt clockwise to increase pressure, and retighten the nut after adjustment.
12. If oil leakage or abnormal noise is found, promptly check seals and internal valve components, and replace worn parts in time.

VI. Comparison with 007 Series

• 01 Series: Maximum flow rate 60 L/min, maximum working pressure 35 MPa, adopts D03 mounting surface standard, suitable for medium and large hydraulic systems with high pressure and large flow requirements.
• 007 Series: Maximum flow rate 25 L/min, maximum working pressure 25 MPa, adopts ISO 4401-02-01-0-05 mounting surface standard, suitable for small and medium hydraulic systems.
