The Sun Hydraulics DNDCXBN928 (DNDCXBN928) is a direct-acting, solenoid-operated, 4-way, 3-position spool valve that is spring-centered to the neutral position. This robust valve is designed for applications requiring precise flow control, with the ability to direct flow between ports based on coil activation. When coil A is energized, it directs flow from port 3 P to port 2 A and from port 4 B to port 1 T, while energizing coil B redirects flow from port 3 to port 4 and from port 2 to port 1. The valve's design incorporates a fatigue-rated solenoid tube assembly capable of handling up to 5000 psi (350 bar), ensuring durability in demanding conditions. The DNDCXBN928 operates without the need for minimum hydraulic pressure due to its direct actuation. It features a wet armature design where the working fluid surrounds the armature, which can impact performance if exposed to heat for prolonged periods. This makes it crucial for users working with certain fluids like water-glycol mixtures that may degrade at high temperatures. The valve offers versatility with various coil termination and voltage options, including configurations with surge protection. The unique magnetic design of the solenoid enhances efficiency by providing high spool actuating force per watt consumed, ensuring reliable operation even at high switching frequencies up to 15,000 cycles per hour. Additionally, interchangeable coils compatible with other Sun Series 1 solenoid products allow flexibility in installation and orientation. With a capacity of up to 5 gpm (20 L/min) and minimal leakage rates under specified conditions, this valve is suitable for diverse hydraulic systems. Its floating style construction minimizes internal binding risks due to installation torque or machining variations. Available seal kits ensure compatibility with different fluid types while maintaining performance integrity across various environmental conditions.
