DFA & DFB-02 Directional Valve | DFA-02-3C2 | DFB-02-3C4 | AC110V/DC12V

DFA/DFB-02 Series Solenoid Directional Control Valves (NG6)

Product Overview: The DFA and DFB-02 Series are among the most versatile high-performance solenoid directional valves in the industrial hydraulic market. Featuring a standard Size 02 (NG6 / CETOP 3) mounting interface, the core strength of this series lies in its 35C (350 Bar) high-pressure rating and a vast array of spool configurations. The DFA Series typically features AC-driven solenoids, while the DFB Series incorporates wet-pin solenoid structures for superior heat dissipation and low-noise operation. Whether used for logic control in automated lines or as a pilot stage for larger valves, this series ensures exceptional switching reliability.

Featured models include the Three-position closed-center 3C2, the H-type 3C4, and various voltage options including AC110V and DC12V.

Key Technical Advantages:

• High Pressure & Flow Capacity: Rated for operating pressures up to 350 Bar (5000 PSI), with flow passages designed to minimize system pressure drop.

• Diverse Spool Functions: Available in 3C2 (Closed center), 3C3 (Open center), 3C4 (H-type), 3C6, and more to fit any actuator logic.

• Low Power Consumption: Optimized solenoid coils provide rapid response times and low temperature rise, supporting high-frequency 24/7 operation.

• Universal Compatibility: Standard ISO 4401 interface allows for seamless interchangeability with NG6 valves from brands like Yuken and Rexroth.
