The Sun Hydraulics DNDCXWN528 (DNDCXWN528) is a direct acting, solenoid-operated, 4-way, 3-position spool valve designed to be spring-centered to the neutral position. This versatile valve offers precise flow control, with coil A energization directing flow from port 3 P to port 2 A and from port 4 B to port 1 T, while coil B energization directs flow from port 3 to port 4 and from port 2 to port 1. It is fatigue-rated for service up to 5000 psi (350 bar) and operates efficiently without requiring minimum hydraulic pressure. Ideal for differential flow circuits, it effectively manages higher return flows through specific ports. The valve is compatible with phosphate ester fluids when equipped with EPDM seals; however, exposure to petroleum-based fluids can damage these seals. Featuring a wet armature design, the valve's working fluid surrounds the armature and absorbs heat generated by the coil\u2014important for applications where coils are energized for extended periods. Fluids like water-glycol mixtures may degrade under these conditions over time. The solenoid's magnetic design ensures high efficiency by providing substantial spool actuating force per watt expended, ensuring reliable operation with interchangeable coils across Sun Series 1 solenoid products. These coils can be mounted in either direction and offer various termination and voltage options, including IP69K-rated connectors for enhanced environmental protection. The DNDCXWN528 incorporates Sun's floating style construction, minimizing internal part binding due to excessive installation torque or machining variations. With a capacity of up to 5 gpm (20 L/min) and a typical response time of 50 ms, this valve supports high-frequency switching at up to 15,000 cycles per hour. It also features a maximum leakage rate of 10 in\u00b3/min at 110 SUS (3000 psi), making it suitable for precision applications in demanding environments.

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.
