The Sun Hydraulics DNDCXHV724N (DNDCXHV724N) is a direct acting, solenoid-operated, 4-way, 3-position spool valve designed for precise hydraulic flow control. This valve is spring-centered to the neutral position and offers two distinct flow paths depending on which coil is energized. When coil A is activated, fluid flows 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. With a fatigue-rated solenoid tube assembly capable of handling up to 5000 psi (350 bar), this valve operates efficiently without requiring a minimum hydraulic pressure. The DNDCXHV724N features a wet armature design that allows the working fluid to surround the armature, which can impact performance if the coil remains energized for extended periods. This design consideration is particularly important when using fluids like water-glycol mixtures that may degrade at elevated temperatures. The valve's high-efficiency solenoid provides substantial spool actuating force per watt, ensuring reliable operation and minimizing internal binding risks due to its floating style construction. This model supports various coil termination and voltage options, some offering surge protection with weatherized coils available for enhanced environmental resilience. It accommodates interchangeable coils with other Sun Series 1 solenoid products, boasting connector options rated up to IP69K for robust protection against environmental elements. Designed for cavity T31A in Series 1 applications, it boasts a capacity of up to 5 gpm (20 L/min) with a typical response time of around 50 ms. The valve has low leakage rates and can handle switching frequencies up to 15,000 cycles per hour. Installation requires torque between 30-35 lbf ft (41-47 Nm), facilitated by its .75-inch (19 mm) solenoid tube diameter and .78-inch (22.2 mm) hex size.

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.
