The Sun Hydraulics DNDCXWN712 (DNDCXWN712) is a direct-acting, solenoid-operated, 4-way, 3-position spool valve designed for high-performance applications requiring precise flow control. This valve is spring-centered to the neutral position, ensuring reliable operation when not energized. When coil A is activated, it directs flow from port 3 P to port 2 A and from port 4 B to port 1 T. Conversely, energizing coil B reroutes the flow from port 3 to port 4 and from port 2 to port 1. The solenoid tube assembly is engineered for fatigue resistance up to a maximum operating pressure of 5000 psi (350 bar), making it suitable for demanding environments. The DNDCXWN712 valve requires no minimum hydraulic pressure for activation due to its direct actuation design. It features a wet armature design where the working fluid surrounds the armature, which can impact performance if the coil remains energized for extended periods. Notably, some fluids like water-glycol mixtures may degrade under such conditions and form varnishes that could affect functionality. This model offers versatility with various coil termination and voltage options available, including surge protection configurations. Its high-efficiency solenoid design provides significant spool actuating force per watt consumed, ensuring dependable valve shifting. The coils are compatible with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. Additional features include IP69K-rated coil connector options for enhanced environmental protection and interchangeable coils for flexible usage across different setups. The valve incorporates Sun's floating style construction to mitigate internal binding risks due to installation torque or machining variations. With a capacity of handling up to 5 gpm (20 L/min), this model presents an optimal solution for applications requiring robust performance and reliability in fluid control systems.

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.
