Northman Type DFA & DFB Solenoid Valve | DFB-02-3C2 | DFA-02-3C4 | AC220V 24V DC | 35MPa Hydraulic Valve

DFA & DFB Series High-Pressure Solenoid Directional Valves

Product Overview: The DFA and DFB series are pivotal components for precision flow direction control in hydraulic systems. These directional valves feature subplate mounting compliant with ISO 4401 international standards. The primary advantage lies in the high-performance wet-pin solenoid technology, where the armature operates within the fluid. This ensures superior heat dissipation while significantly reducing mechanical shock and noise during switching. The 35C design series is specifically optimized for high-pressure conditions, supporting up to 35 MPa, making it ideal for heavy-duty industrial machinery and precision control circuits.

Featured models include: DFB-02-2B2-AC220-35C-13F, DFB-02-3C2-AC220-35C-13F, and DFA-02-3C4-024-35C.

Key Technical Advantages:

• High-Pressure Reliability (35C): Engineered with high-strength castings, these valves are rated for pressures up to 35 MPa (350 bar), meeting the rigorous demands of modern hydraulics.

• Wet-Pin Solenoid Architecture: The oil-immersed armature eliminates external dynamic seal leaks and utilizes hydraulic damping to extend spool service life.

• Flexible Electrical Options: Available in AC220V and DC24V (Model 024) specifications, with optional indicator light connectors for easy on-site troubleshooting.

• Versatile Spool Configurations: Supports various logic like 3C2 (Closed Center), 3C4 (H-type Center), and 2B2 (2-position) to suit complex circuit requirements.
