The Sun Hydraulics DNDCXBN712 (DNDCXBN712) is a direct acting, solenoid-operated, 4-way, 3-position spool valve designed for high-efficiency hydraulic systems. This valve is spring-centered to the neutral position and operates by energizing coils to control fluid flow direction. When coil A is energized, flow occurs from port 3 P to port 2 A and from port 4 B to port 1 T. Conversely, 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 up to 5000 psi (350 bar), ensuring durability in demanding applications. This valve does not require a minimum hydraulic pressure for operation, making it versatile for various systems. The DNDCXBN712 features a wet armature design, where the working fluid surrounds the armature and absorbs heat generated by the coil. This design consideration is crucial for long periods of coil energization as certain fluids may degrade under heat exposure over time. The valve accommodates a wide array of coil termination and voltage options, enhancing its adaptability in different configurations. With a capacity of handling up to 5 gpm (20 L/min) and a maximum operating pressure of 5000 psi (350 bar), this valve provides reliable performance with minimal leakage at specified conditions. It incorporates Sun's floating style construction, reducing the risk of internal binding due to installation torque or machining variations. The high-efficiency solenoid design delivers significant spool actuating force per watt expended, ensuring dependable valve shifting. For enhanced environmental protection, weatherized coils and kits are available, with connector options rated up to IP69K. The interchangeable coils can be mounted in either direction on the tube, offering flexibility in installation. Additionally, cartridges with EPDM seals are suitable for phosphate ester fluid systems but should avoid petroleum-based fluids due to potential seal damage.

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.
