The Sun Hydraulics DNDCXRN724N (Material Number: DNDCXRN724N) is a direct-acting, solenoid-operated, 4-way, 3-position spool valve designed for efficient hydraulic flow management. This valve is spring-centered to maintain a neutral position when not energized. Upon energizing coil A, the flow transitions 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 solenoid tube assembly is robustly rated for service pressures up to 5000 psi (350 bar), ensuring durability under demanding conditions. This valve operates without requiring a minimum hydraulic pressure, making it versatile for various applications. In systems with differential flow circuits, it is recommended that higher return flows be directed through port 2 A to port 1 T. The valve's wet armature design allows the working fluid to cool the armature but requires careful consideration of fluid types due to potential breakdown at high temperatures. Sun Hydraulics offers a range of coil termination and voltage options, with some configurations providing surge protection and IP69K ratings for enhanced environmental resistance. The high-efficiency solenoid design ensures reliable valve shifting by maximizing spool actuating force per watt consumed. Coils are interchangeable with other Sun Series 1 products, offering flexibility in installation orientation. The DNDCXRN724N incorporates Sun's floating style construction, reducing the risk of internal component binding due to installation torque or machining variations. It features a cavity size of T-31A and supports a capacity of up to 5 gpm (20 L/min). With a typical response time of around 50 ms and capable of handling switching frequencies up to 15,000 cycles per hour, this valve is engineered for high-performance hydraulic systems requiring precision control and reliability.
