The Sun Hydraulics DNDCXWN211 (Material Number: DNDCXWN211) is a direct acting, solenoid-operated, 4-way, 3-position spool valve designed to be spring-centered to a neutral position. This valve efficiently manages flow direction based on coil activation; 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. Built for robust performance, the solenoid tube assembly is fatigue-rated for service at pressures up to 5000 psi (350 bar), and the valve operates without requiring a minimum hydraulic pressure. In differential flow circuits, optimal performance is achieved by directing higher return flows through port 2 A to port 1 T. The valve features a wet armature design where the working fluid surrounds the armature, which can be affected by heat generated during prolonged coil activation. EPDM seals are used for systems with phosphate ester fluids but can degrade with petroleum-based substances. The solenoid's magnetic design provides high efficiency and reliable shifting with minimal energy expenditure. Coils are interchangeable with other Sun Series 1 products and offer various termination and voltage options, including models with surge protection and weatherized configurations for enhanced environmental resistance. Incorporating Sun\u2019s floating style construction reduces risks of internal part binding due to installation torque or machining variations. The DNDCXWN211 has a capacity of up to 5 gpm (20 L/min) and demonstrates rapid response times of approximately 50 ms. It maintains low leakage rates under pressure and supports high switching frequencies up to 15,000 cycles per hour. The valve's installation requires specific torque settings, ensuring secure placement within its designated cavity size T-31A.

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.
