The Sun Hydraulics DNDCXHE928 (Material Number: DNDCXHE928) is a direct acting, solenoid-operated, 4-way, 3-position spool valve designed for applications requiring precise flow control. This valve is spring-centered to a neutral position and offers versatile flow configurations depending on the energization of the coils. 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 solenoid tube assembly is robustly built for fatigue resistance up to a service pressure of 5000 psi (350 bar), ensuring durability in demanding environments. The valve's direct actuation requires no minimum hydraulic pressure for operation, making it suitable for various hydraulic systems. In differential flow circuits, directing higher return flows through specific ports optimizes performance. The cartridge with EPDM seals should be used exclusively with phosphate ester fluids due to potential damage from petroleum-based substances. Featuring a wet armature design, the valve efficiently dissipates heat generated by the coil; however, users should be mindful of fluid compatibility at elevated temperatures. Offering a range of coil termination and voltage options, this model supports customization for specific needs while maintaining high efficiency with its unique magnetic design. Coils are interchangeable within the Sun Series 1 solenoid products line and can be mounted bidirectionally on the tube. The valve incorporates Sun's floating style construction to minimize internal binding risks due to installation torque variations or machining inconsistencies. With a capacity of up to 5 gpm (20 L/min) and typical response time of approximately 50 ms, this spool valve is engineered for reliable performance with minimal leakage under specified conditions. Coil connector options provide protection ratings up to IP69K, ensuring resilience against environmental factors.

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.
