DHA Series High-Performance Direct-Operated Solenoid Valves

Product Overview: The DHA series comprises direct-operated 3 or 4-way solenoid directional valves engineered for demanding industrial applications. These valves feature high-performance wet-pin solenoids, where the armature operates within the fluid, providing natural damping of mechanical shock and enhanced heat dissipation. Their compact footprint and diverse spool functions (such as 0631/2 and 0718) make them perfect for precision machine tools, automated production lines, and mobile hydraulic control circuits. The -M option indicates a manual override feature, allowing for manual actuator control during power loss or system commissioning.

Featured models include: DHA-0631/2/M-24DC, DHA-0713/M-24DC, DHA-0631/2/A/M-24DC, and DHA-0718/M-24DC.

Key Technical Advantages:

• Zero-Leakage Wet-Pin Design: The static-seal solenoid architecture eliminates external oil leaks at the pushrod, ensuring a cleaner operational environment.

• Rapid Response Switching: The direct-acting design drives the spool immediately, resulting in minimal switching lag for high-frequency duty cycles.

• Manual Override (M): Equipped with a manual push-button/pin for quick testing during maintenance or troubleshooting procedures.

• Versatile Logic Configurations: Includes a wide range of combinations like the 0713 (2/3-way) and 0631 (3/4-way) to suit various hydraulic actuator requirements.
