The Sun Hydraulics DNDCXAN624 (DNDCXAN624) is a direct acting, solenoid-operated, 4-way, 3-position spool valve designed for precision flow control in hydraulic systems. This valve is spring-centered to the neutral position, enabling versatile flow configurations based on coil activation. When coil A is energized, fluid flows from port 3 P to port 2 A and from port 4 B to port 1 T. Conversely, energizing coil B directs flow from port 3 to port 4 and from port 2 to port 1. The valve operates efficiently under high-pressure conditions with a fatigue rating of up to 5000 psi (350 bar), making it suitable for demanding hydraulic applications. The DNDCXAN624 does not require a minimum hydraulic pressure for operation, which enhances its applicability in various systems. It features a wet armature design that allows the working fluid to surround the armature, absorbing heat generated by the coil\u2014a critical consideration during prolonged energization periods. Notably, fluids like water-glycol mixtures may degrade at these temperatures over time. This model supports various coil termination and voltage options with or without surge protection, ensuring adaptability across different setups. Its high-efficiency solenoid design provides reliable valve shifting through significant spool actuating force per watt expended. The interchangeable coils within Sun Series 1 products offer flexibility in installation direction and environmental protection options up to IP69K ratings. The valve incorporates Sun's floating style construction to reduce binding risks due to installation torque or machining variations. It fits into cavity T-31A and has a capacity of 5 gpm (20 L/min). With a typical response time of 50 ms and capable of handling switching frequencies up to 15,000 cycles per hour, this robust valve is optimized for performance in complex hydraulic circuits requiring precise control and reliability.
