The Sun Hydraulics DNDCXTN211 (DNDCXTN211) is a direct acting, solenoid-operated, 4-way, 3-position spool valve designed for high performance in hydraulic systems. This valve is spring-centered to the neutral position and facilitates directional flow control by energizing either coil A or B. 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 at pressures up to 5000 psi (350 bar), ensuring reliable operation without requiring a minimum hydraulic pressure. The DNDCXTN211 incorporates a wet armature design that allows the working fluid to encase the armature, potentially affecting performance if fluids like water-glycol mixtures degrade under prolonged heat exposure. This valve supports various coil termination and voltage configurations with optional surge protection, providing flexibility in diverse applications. Its high-efficiency solenoid design delivers significant spool actuating force per Watt used, enhancing valve shifting reliability. Interchangeable coils with other Sun Series 1 products allow easy installation in either direction on the tube. Coil connectors are available with ratings up to IP69K for superior environmental protection, including additional weatherized options for harsh conditions. The DNDCXTN211 features Sun's floating style construction to minimize binding risks due to installation torque or machining variations. With a capacity of handling flows up to 5 gpm (20 L/min) and a typical response time of just 50 ms, this spool valve is suitable for applications requiring quick and precise fluid control. It offers maximum versatility with Viton seal kits available for both cartridge and coil applications, ensuring compatibility with various fluid types while maintaining optimal sealing integrity.

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.
