The Sun Hydraulics DNDCXBE528 (DNDCXBE528) is a direct acting, solenoid-operated, 4-way, 3-position spool valve designed for precise fluid control in hydraulic systems. This valve is spring-centered to the neutral position and offers two flow paths depending on which coil is energized. When coil A is activated, the flow moves 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. The valve boasts a fatigue-rated solenoid tube assembly capable of handling up to 5000 psi (350 bar), ensuring durability under high-pressure conditions. This model requires no minimum hydraulic pressure for operation, making it suitable for various applications, including those with differential flow circuits where higher return flows need routing through specific ports. It features EPDM seals compatible with phosphate ester fluids but cautions against exposure to petroleum-based substances. The wet armature design enhances efficiency but may affect certain fluids like water-glycol mixtures over time due to heat exposure. The DNDCXBE528 offers flexible configuration options with a variety of coil terminations and voltage choices available, some with surge protection. Its efficient magnetic design provides high spool actuating force per Watt expended, ensuring reliable performance. Coils are interchangeable within the Sun Series 1 range and can be mounted in either direction on the tube. Additional weatherized coils are available for enhanced environmental protection. Key specifications include a capacity of 5 gpm (20 L/min), a typical response time of 50 ms, and maximum valve leakage at specified conditions of up to 10 in\u00b3/min (160 cc/min). The valve's construction minimizes internal part binding risks due to excessive installation torque or machining variations, making it robust and reliable for demanding hydraulic applications.

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.
