The Sun Hydraulics DNDCXAE224N (Material Number: DNDCXAE224N) is a direct acting, solenoid-operated, 4-way, 3-position spool valve that is spring-centered to the neutral position. This versatile valve is designed for applications requiring precise flow control and reliable operation. When coil A is energized, the fluid flows from port 3 P to port 2 A and from port 4 B to port 1 T. Conversely, energizing coil B directs the flow from port 3 to port 4 and from port 2 to port 1. The valve's solenoid tube assembly is fatigue-rated for a service pressure of up to 5000 psi (350 bar), ensuring durability under demanding conditions. The DNDCXAE224N operates without the need for minimum hydraulic pressure due to its direct actuation design. It features a wet armature design, which allows the working fluid to surround the armature and be exposed to heat generated by the coil\u2014a consideration for prolonged energization periods. For differential flow circuits, it is recommended that higher return flows be routed through port 2 A to port 1 T. This model supports a variety of coil termination and voltage options, with additional features like surge protection available. Its solenoid design results in high efficiency by providing substantial spool actuating force per watt expended, enhancing reliability in valve shifting operations. The coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. The valve incorporates Sun's floating style construction, minimizing potential binding of internal parts due to excessive installation torque or machining variations in cavity/cartridge assemblies. Additionally, it offers robust environmental protection options with coil connector ratings up to IP69K and weatherized kits available for enhanced durability in harsh conditions. The DNDCXAE224N has a capacity of up to 5 gpm (20 L/min) with a typical response time of approximately 50 ms and supports switching frequencies up to 15,000 cycles per hour.
