The Sun Hydraulics DNDCXCV211 (DNDCXCV211) is a direct acting, solenoid-operated, 4-way, 3-position spool valve designed for high-efficiency hydraulic applications. This valve is engineered to be spring-centered to the neutral position, ensuring stable operation when not energized. When coil A is activated, hydraulic flow transitions from port 3 P to port 2 A and from port 4 B to port 1 T. Conversely, energizing coil B redirects flow from port 3 to port 4 and from port 2 to port 1. The solenoid tube assembly is robustly fatigue-rated for service up to 5000 psi (350 bar), making it suitable for demanding environments. This valve does not require a minimum hydraulic pressure for operation, making it versatile in various applications. For differential flow circuits, directing the higher return flow through port 2 A to port 1 T is recommended. It features EPDM seals compatible with phosphate ester fluids but caution should be exercised as exposure to petroleum-based fluids can damage these seals. The DNDCXCV211 employs a wet armature design; the working fluid surrounds the armature and absorbs heat generated by the coil\u2014a consideration for prolonged coil activation as certain fluids may degrade over time under these conditions. The valve offers various coil termination and voltage options, including configurations with surge protection. Its unique magnetic design enhances efficiency by delivering high spool actuating force per watt expended. Coils are interchangeable with other Sun Series 1 solenoid products and can be mounted bidirectionally on the tube. Coil connector options provide ratings up to IP69K for enhanced environmental protection. Additionally, this model incorporates Sun's floating style construction to minimize internal part binding due to installation torque or machining variations within the cavity or cartridge. With a capacity of up to 5 gpm (20 L/min) and a typical response time of approximately 50 ms, this valve supports frequent switching with minimal leakage at high pressures.

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.
