The Sun Hydraulics DNDCXTN924N (DNDCXTN924N) is a direct-acting, solenoid-operated, 4-way, 3-position spool valve designed for hydraulic systems requiring precise control of fluid direction. This valve is spring-centered to a neutral position and features a robust solenoid tube assembly rated for fatigue at 5000 psi (350 bar), ensuring reliable performance under high-pressure conditions. The valve operates efficiently without the need for minimum hydraulic pressure, making it suitable for various applications where direct actuation is essential. When coil A is energized, the flow direction is from port 3 P to port 2 A and from port 4 B to port 1 T. Conversely, energizing coil B redirects the flow from port 3 to port 4 and from port 2 to port 1. The valve employs a wet armature design, allowing the working fluid to surround the armature and absorb heat generated by the coil. This feature requires consideration when using fluids sensitive to temperature changes over prolonged periods. The DNDCXTN924N offers flexibility with interchangeable coils compatible with other Sun Series 1 solenoid products, available in various termination and voltage options including those with surge protection. Its unique magnetic design enhances efficiency by delivering high spool actuating force per watt expended, ensuring dependable valve shifting even in demanding environments. The valve's construction incorporates Sun's floating style design to reduce internal binding risks due to installation torque or machining variations. With a capacity of up to 5 gpm (20 L/min) and operating pressure limits of up to 5000 psi (350 bar), this spool valve is suitable for differential flow circuits where higher return flows should be routed through specific ports as specified. It also supports high-frequency switching up to 15,000 cycles per hour with minimal leakage rates at specified viscosities. Optional weatherized coils are available for enhanced environmental protection, making this valve versatile across diverse applications requiring robust hydraulic control solutions.
