The Sun Hydraulics DNDCXWE928 (DNDCXWE928) is a versatile direct-acting, solenoid-operated, 4-way, 3-position spool valve designed for efficient hydraulic control. This valve is spring-centered to the neutral position and offers precise flow control depending on the coil activated. When coil A is energized, the flow transitions 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 solenoid tube assembly is robustly constructed for fatigue resistance at service pressures up to 5000 psi (350 bar). This direct-actuated valve does not require a minimum hydraulic pressure for operation, making it suitable for various applications. In differential flow circuits, it's recommended that higher return flows are directed through port 2 A to port 1 T. The valve features EPDM seals compatible with phosphate ester fluids but may degrade if exposed to petroleum-based substances. Its wet armature design ensures operational fluid surrounds the armature, which can be affected by prolonged coil energization due to heat exposure\u2014particularly relevant for water-glycol mixtures that may degrade over time. The DNDCXWE928 offers multiple coil termination and voltage options, including surge protection configurations. Its high-efficiency solenoid design ensures reliable shifting with substantial spool actuating force per watt expended. Coils are interchangeable with other Sun Series 1 products and can be mounted bidirectionally on the tube. Connector options provide ratings up to IP69K for enhanced environmental protection. The valve incorporates Sun's floating style construction, minimizing internal part binding risks due to excessive installation torque or machining variations in cavity/cartridge interfaces. With a capacity of up to 5 gpm (20 L/min), typical response time of approximately 50 ms, and maximum leakage of 10 in\u00b3/min at specified conditions, this model is engineered for high performance in demanding environments.

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.
