The Sun Hydraulics DNDCXCN812N (Material Number: DNDCXCN812N) is a direct acting, solenoid-operated, 4-way, 3-position spool valve designed for reliable hydraulic flow control. This valve is spring-centered to a neutral position and provides precise directional flow when energized; coil A allows flow from port 3 P to port 2 A and from port 4 B to port 1 T, while coil B directs flow from port 3 to port 4 and from port 2 to port 1. It features a robust solenoid tube assembly rated for fatigue at up to 5000 psi (350 bar), ensuring durability in high-pressure environments. The valve does not require minimum hydraulic pressure for operation, making it versatile for various applications. Designed with a wet armature configuration, the working fluid surrounds the armature, which can be subjected to heat generated by the coil. This design consideration is crucial as some fluids may degrade under prolonged exposure to heat. The valve supports differential flow circuits by directing higher return flows through specific ports. It also offers compatibility with EPDM seals for systems utilizing phosphate ester fluids. The DNDCXCN812N incorporates Sun's unique floating style construction, minimizing internal part binding due to installation torque or machining variations. Its high-efficiency solenoid provides significant spool actuating force per watt expended, ensuring dependable valve shifting. The product supports various coil termination and voltage options with interchangeable coils compatible within the Sun Series 1 range. Coil connector options are available with protection ratings up to IP69K for enhanced environmental resilience. This model fits into cavity T-31A and operates with a capacity of up to 5 gpm (20 L/min). It has a typical response time of approximately 50 ms and can handle switching frequencies of up to 15,000 cycles per hour. The maximum valve leakage rate is minimal at specified conditions, ensuring efficient performance in demanding applications.

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.
