The Sun Hydraulics DNDCXBN848 (DNDCXBN848) 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 and features a unique wet armature design, which allows the working fluid to surround the armature. This design aspect is crucial for applications where the coil may be energized for extended periods, as certain fluids can degrade at high temperatures. The valve operates efficiently with no minimum hydraulic pressure required, making it suitable for various hydraulic systems. It has a fatigue-rated solenoid tube assembly capable of handling up to 5000 psi (350 bar), ensuring durability and reliability in demanding environments. The DNDCXBN848 is engineered with high efficiency in mind; its magnetic design maximizes spool actuating force per watt expended, ensuring reliable shifting of the valve. It supports a wide range of coil termination and voltage options, including configurations with surge protection and IP69K-rated connectors for enhanced environmental resistance. The interchangeable coils are compatible with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. With a capacity of 5 gpm (20 L/min) and a typical response time of 50 milliseconds, this valve offers rapid switching capabilities up to 15,000 cycles per hour. Its construction incorporates Sun's floating style to minimize internal binding from installation torque or machining variations. The valve's cavity is T-31A series compatible, and it requires an installation torque between 30-35 lbf-ft (41-47 Nm). For systems using phosphate ester fluids, cartridges with EPDM seals are recommended to prevent seal damage from petroleum-based substances.

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.
