4WE6GA Solenoid Directional Valve

I. Core Structure and Function

Wet-Type Solenoid Design

Utilizes wet-type AC/DC solenoids with fully enclosed internal insulation. The armature moves within the oil medium, reducing wear and improving heat dissipation efficiency, thereby extending service life.

The control spool is driven by the solenoid push rod. When de-energized, the return spring automatically resets it to the neutral or initial position.

Modularity and Compatibility

Complies with ISO 4401-03-02-0-05 port standards, supports subplate or threaded connections, and adapts to various hydraulic system integration requirements.

Optional auxiliary manual button allows manual spool position switching during power loss (available for certain models).

III. Application Scenarios

Construction Machinery

Used for directional control in hydraulic systems of excavators and cranes, driving actuators (such as cylinders and motors) for directional changes.

Industrial Automation

Hydraulic control units for metallurgical equipment and forging presses, working in conjunction with cartridge valves to achieve precise high-pressure fluid directional changes.

Energy and Marine

Suitable for ship deck machinery, wind power hydraulic stations, and other scenarios requiring frequent start-stop operations and high reliability.

IV. Product Advantages

High-Pressure Adaptability: Supports high-pressure environments of 25~33.5MPa, meeting the demands of heavy-duty equipment.

High Flow Capacity: Cast internal passage design reduces pressure loss, with flow rates up to 80L/min (for certain models).

Safety Certification: Solenoid coils are UL 906 and CSA C22.2 certified, ensuring electrical safety.

Easy Maintenance: Modular structure supports quick disassembly and assembly; optional fluororubber seals enhance corrosion resistance.

V. Customization and Services

Seal Materials: Optional polyurethane or fluororubber seals to suit high-temperature or corrosive media.

Electrical Configuration: Provides centralized or distributed electrical interfaces to adapt to different control system layouts.

System Integration: Supports coordinated debugging with TRM series multi-way valves or cartridge valve systems, reducing integration complexity.
