The Sun Hydraulics DNDCXAE912N (DNDCXAE912N) is a direct acting, solenoid-operated, 4-way, 3-position spool valve designed for precise hydraulic control applications. This valve is spring-centered to the neutral position, ensuring stability and reliability when not in operation. When coil A is energized, the flow path is directed 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 valve features a fatigue-rated solenoid tube assembly capable of handling up to 5000 psi (350 bar) service pressure, making it suitable for demanding environments. The DNDCXAE912N requires no minimum hydraulic pressure for operation due to its direct actuation design. It is particularly effective in differential flow circuits by directing the higher return flow through specific ports. The use of EPDM seals makes this valve compatible with phosphate ester fluids while cautioning against exposure to petroleum-based substances which could damage the seals. Additionally, the valve incorporates a wet armature design that allows the working fluid to surround the armature, which can be crucial when considering heat generation during prolonged coil energization. Various coil termination and voltage options are available, including configurations with surge protection. The high-efficiency solenoid design offers significant spool actuating force per watt expended. The DNDCXAE912N also features interchangeable coils with other Sun Series 1 solenoid products and offers several connector options rated up to IP69K for enhanced environmental protection. Its floating style construction minimizes internal binding risks due to installation torque or machining variations. With a capacity of 5 gpm (20 L/min) and a typical response time of 50 ms, this valve supports high-frequency switching up to 15,000 cycles/hr while maintaining low leakage rates under specified conditions.

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.
