The Sun Hydraulics DNDCXBE948 (DNDCXBE948) 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 the neutral position and features a unique wet armature design that ensures efficient heat dissipation while maintaining optimal performance. The valve operates at a maximum pressure of 5000 psi (350 bar) and has a capacity of 5 gpm (20 L/min). It is engineered for high-frequency switching with a typical response time of 50 ms and can handle up to 15,000 cycles per hour. The DNDCXBE948 offers versatile flow configurations: when coil A is energized, fluid flows from port 3 P to port 2 A and from port 4 B to port 1 T; when coil B is energized, flow direction changes from port 3 to port 4 and from port 2 to port 1. It requires no minimum hydraulic pressure for operation, making it suitable for various applications without the need for additional pilot pressure. This valve incorporates Sun's floating style construction, which reduces the risk of internal component binding due to installation torque or machining variations. It supports multiple coil termination and voltage options with surge protection capabilities, ensuring adaptability across different system requirements. The coils are interchangeable with other Sun Series 1 solenoid products and offer IP69K-rated connector options for enhanced environmental protection. Additionally, the valve's design accommodates differential flow circuits by directing higher return flows through specific ports, optimizing system efficiency. For use with phosphate ester fluids, cartridges equipped with EPDM seals are available; however, these seals should not be exposed to petroleum-based fluids. The DNDCXBE948's high-efficiency solenoid provides reliable valve shifting by delivering substantial spool actuating force per watt expended.

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.
