The Sun Hydraulics DNDCXCN299 (DNDCXCN299) is a direct acting, solenoid-operated, 4-way, 3-position spool valve designed for high-efficiency and reliability in hydraulic systems. This valve is spring-centered to the neutral position, allowing for controlled fluid flow when either coil A or coil B is energized. Specifically, energizing coil A directs flow from port 3 P to port 2 A and from port 4 B to port 1 T, while energizing coil B directs flow from port 3 to port 4 and from port 2 to port 1. The solenoid tube assembly is fatigue-rated for service up to 5000 psi (350 bar), ensuring durability under high-pressure conditions. The valve operates without the need for minimum hydraulic pressure, making it suitable for various applications where direct actuation is necessary. It features a wet armature design that exposes the armature to the working fluid, which can be crucial in managing heat generated by long-term coil energization. The DNDCXCN299 accommodates different fluids with EPDM seals specifically recommended for systems using phosphate ester fluids while avoiding petroleum-based substances that could damage the seals. This model offers a range of coil termination and voltage options, with some configurations providing surge protection and environmental resilience up to IP69K ratings. The interchangeable coils are compatible with other Sun Series 1 solenoid products. Additionally, the valve incorporates Sun's floating style construction technique to reduce the risk of internal binding due to installation torque or cavity variations. With a capacity of handling flow rates up to 5 gpm (20 L/min) and a rapid typical response time of approximately 50 ms, this spool valve is engineered for high-frequency switching up to 15,000 cycles per hour. Its robust design makes it a versatile component in demanding hydraulic applications requiring precise control and reliability.

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.
