The Sun Hydraulics DNDCXRE528 (Material Number: DNDCXRE528) is a direct acting, solenoid-operated, 4-way, 3-position spool valve designed for precision fluid control in hydraulic systems. This valve is spring-centered to a neutral position, allowing for controlled flow direction when either coil A or coil B is energized. Specifically, energizing coil A directs flow from port 3 P to port 2 A and from port 4 B to port 1 T, while energizing coil B redirects flow from port 3 to port 4 and from port 2 to port 1. The valve's solenoid tube assembly is fatigue-rated for service up to 5000 psi (350 bar), ensuring durability and reliability under high-pressure conditions. This model requires no minimum hydraulic pressure for operation, making it suitable for various applications where differential flow circuits are present. The design incorporates EPDM seals ideal for phosphate ester fluid systems but cautions against exposure to petroleum-based fluids due to potential seal damage. The wet armature design enhances thermal management by exposing the armature to the working fluid, though users should be mindful of potential varnish formation with certain fluids under prolonged coil energization. The DNDCXRE528 offers a range of coil termination and voltage options with surge protection capabilities, enhancing its adaptability across different setups. Its high-efficiency solenoid design ensures reliable valve shifting with minimal energy expenditure. The interchangeable coils are compatible with other Sun Series 1 solenoid products and can be mounted bi-directionally on the tube. With options available up to IP69K ratings, the valve provides robust environmental protection. Additional features include Sun's floating style construction that minimizes internal component binding due to installation torque or machining variations. It fits into a T-31A cavity and has a capacity of up to 5 gpm (20 L/min), making it versatile for various hydraulic applications requiring precise directional control.

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.
