The Sun Hydraulics DNDCXYN528 (DNDCXYN528) is a direct-acting, solenoid-operated, 4-way, 3-position spool valve designed to be spring-centered to the neutral position. This versatile valve allows for precise control over hydraulic flow; when coil A is energized, flow is directed from port 3 P to port 2 A and from port 4 B to port 1 T. Conversely, energizing coil B shifts the flow from port 3 to port 4 and from port 2 to port 1. The solenoid tube assembly is robustly built to handle fatigue at service pressures up to 5000 psi (350 bar), ensuring durability and reliability in demanding applications. This valve operates without requiring a minimum hydraulic pressure, making it suitable for various applications where direct actuation is crucial. It features a wet armature design that allows the working fluid to surround the armature, which can be beneficial or detrimental depending on fluid type and exposure time. For example, fluids like water-glycol mixtures may degrade over time due to heat exposure when the coil remains energized for extended periods. The DNDCXYN528 offers flexible coil termination and voltage options with interchangeable coils compatible with other Sun Series 1 solenoid products. Coil connector options provide protection ratings up to IP69K for enhanced environmental resilience. The valve also incorporates Sun's floating style construction, minimizing internal binding risks due to installation torque variations or machining discrepancies. With a capacity of up to 5 gpm (20 L/min) and a rapid typical response time of approximately 50 ms, this valve is engineered for high-efficiency performance. Its switching frequency capability reaches up to 15,000 cycles per hour, making it ideal for applications requiring frequent actuation. Additionally, Viton seal kits are available for both cartridge and coil components, ensuring compatibility with various fluid types while maintaining optimal performance.

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.
