The Sun Hydraulics DNDCXBE928 (Material Number: DNDCXBE928) is a direct acting, solenoid-operated, 4-way, 3-position spool valve designed for precise hydraulic control. This valve is spring-centered to a neutral position, allowing for versatile flow configurations. 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. The valve's solenoid tube assembly is robustly engineered for fatigue resistance at pressures up to 5000 psi (350 bar), ensuring reliable performance in demanding applications. This valve operates without the need for minimum hydraulic pressure, making it ideal for differential flow circuits where higher return flow should be directed through specific ports. It incorporates EPDM seals suitable for systems using phosphate ester fluids; however, these seals are vulnerable to petroleum-based substances. The wet armature design allows the working fluid to cool the armature but may pose challenges with certain fluids under prolonged coil activation due to heat generation. The solenoid's magnetic configuration enhances efficiency by delivering high actuating force per watt consumed, contributing to consistent valve shifting. Coils are interchangeable with other Sun Series 1 products and can be mounted in either direction on the tube. Available coil connector options provide ratings up to IP69K for enhanced environmental protection. The DNDCXBE928 features Sun's floating style construction, minimizing internal binding risks 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). With a typical response time of around 50 ms and a switching frequency of up to 15,000 cycles per hour, this valve offers high performance and durability in various 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.
