Northman Type DFA Valve | DFA-02-3C2 DFA-03-3C60 | NG6 NG10 Solenoid Valve | DC24V

Northman Type DFA Series Solenoid Directional Control Valves

Product Overview: The DFA Series represents a premium line of solenoid-operated spool valves recognized for their stability and extended service life in industrial hydraulic applications. Fully compliant with ISO 4401 mounting standards, this series covers both Size 02 (NG6 / CETOP 3) and Size 03 (NG10 / CETOP 5) footprints. Featuring fluid-dynamically optimized internal flow paths, the DFA series delivers high power output while maintaining minimal pressure drop.

This category highlights essential high-performance configurations: the 3-position closed-center DFA-02-3C2 and the high-capacity DFA-03-3C60. Equipped with high-performance DC24V wet-pin solenoids and specialized design sequences like 14H and 35C, these valves are the premier choice for CNC machine tools, automated production lines, injection molding machinery, hydraulic presses, and mobile power units.

Key Technical Advantages:

• Wet-Pin Solenoid Design: The armature operates fully immersed in hydraulic oil, ensuring superior heat dissipation and internal lubrication. This results in quiet switching and significantly prolonged mechanical life.

• Extreme Pressure & Flow Capacity: Rated for operating pressures up to 31.5 MPa (4,500 PSI). The DFA-03 model handles flows up to 120 L/min, ideal for high-power circuits.

• Anti-Vibration Integrity: Reinforced spring and spool structures ensure reliable commutation even in systems with high pressure pulsations or mechanical vibrations, preventing accidental shifting.

• Robust Electrical Integration: Standard DC24V voltage support with various connector formats. The high protection rating (up to IP65) ensures stable performance in humid or dusty industrial environments.
