The Sun Hydraulics DNDCXAE724N (DNDCXAE724N) is a high-performance, direct-acting, solenoid-operated 4-way, 3-position spool valve designed for precision fluid control in hydraulic systems. This valve is spring-centered to maintain a neutral position when not energized. Upon energizing coil A, 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 flow from port 3 to port 4 and from port 2 to port 1. Built for durability, the solenoid tube assembly is fatigue-rated for service up to 5000 psi (350 bar), ensuring reliable performance under high-pressure conditions. The valve operates without requiring minimum hydraulic pressure due to its direct actuation design. In differential flow circuits, it is recommended that higher return flows be routed through port 2 A to port 1 T for optimal performance. The valve's wet armature design allows the working fluid to surround the armature, which may affect function if the coil remains energized for extended periods due to heat exposure. Notably, certain fluids like water-glycol mixtures can degrade over time under such conditions. This model offers flexibility with various coil termination and voltage options available, including configurations with surge protection. The solenoid's magnetic design ensures efficient operation by providing high spool actuating force per watt consumed. Coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. With a capacity of up to 5 gpm (20 L/min) and a maximum operating pressure of 5000 psi (350 bar), this valve exhibits robust capabilities suited for demanding applications. Its construction minimizes internal binding risks due to excessive installation torque or machining variations in cavity/cartridge interfaces. The DNDCXAE724N also supports IP69K-rated coil connector options for enhanced environmental protection.

This direct acting, solenoid-operated, 4-way, 3-position spool valve is spring centered to the neutral position. When coil A is energized, the flow is from port 3 (P) to port 2 (A) and from port 4 (B) to port 1 (T). When coil B is energized, the flow is from port 3 to port 4 and from port 2 to port 1.
- The solenoid tube assembly is fatigue rated for 5000 psi (350 bar) service.
- This valve is direct actuated and requires no minimum hydraulic pressure for operation.
- In differential flow circuits, the higher return flow should be directed through port 2 (A) to port 1 (T).
- Cartridges with EPDM seals are for use in systems with phosphate ester fluids. Exposure to petroleum based fluids, greases and lubricants will damage the seals.
- This valve utilizes a wet armature design. This means that the working fluid surrounds the armature and is exposed to the heat generated by the coil. This can be a factor if the coil is energized for long periods of time. Some fluids, notably water/glycol mixtures, break down at these temperatures over time and form varnishes that will affect the function of the cartridge.
- A wide variety of coil termination and voltage options are available, with and without surge protection. See the CONFIGURATION section.
- The solenoid's unique magnetic design results in a high efficiency solenoid, yielding high spool actuating force per Watt expended, leading to reliable valve shifting.
- Coils are interchangeable with other Sun Series 1 solenoid products and can be mounted on the tube in either direction.
- Coil connector options offer ratings up to IP69K. See individual coil product pages for details. Additional weatherized coils and kits are available for more complete environmental protection.
- Incorporates the Sun floating style construction to minimize the possibility of internal parts binding due to excessive installation torque and/or cavity/cartridge machining variations.
