The Sun Hydraulics DNDCXRE224N (DNDCXRE224N) is a direct-acting, solenoid-operated, 4-way, 3-position spool valve engineered for high-efficiency hydraulic applications. This valve is spring-centered to a neutral position and offers two flow paths depending on the coil energized. When coil A is activated, the flow transitions 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. Designed for robustness, the solenoid tube assembly can withstand fatigue at pressures up to 5000 psi (350 bar). The valve operates without requiring a minimum hydraulic pressure, making it versatile for various systems. In differential flow circuits, it's advised that higher return flows be routed through port 2 A to port 1 T. The valve incorporates EPDM seals suitable for phosphate ester fluids but should avoid petroleum-based substances that could degrade the seals. Featuring a wet armature design, the fluid surrounds the armature and absorbs heat generated by the coil\u2014a consideration when using fluids like water-glycol mixtures that may form varnishes over time due to heat exposure. This model offers multiple coil termination and voltage options with potential surge protection configurations. Its magnetic design ensures high efficiency with significant spool actuating force per watt expended, ensuring reliable operation across its lifecycle. Coils are interchangeable with other Sun Series 1 solenoid products and can be installed in either direction on the tube. Additionally, weatherized coils and kits are available for enhanced environmental protection. The DNDCXRE224N integrates Sun's floating style construction to reduce internal binding risks due to excessive installation torque or variations in cavity machining. It features a capacity of up to 5 gpm (20 L/min), a typical response time of approximately 50 ms, and supports switching frequencies up to 15,000 cycles per hour.

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.
