The Sun Hydraulics DNDCXYV212N (DNDCXYV212N) is a direct acting, solenoid-operated, 4-way, 3-position spool valve designed for high-performance hydraulic systems. This valve is spring-centered to the neutral position and allows for precise control of hydraulic flow. When coil A is energized, the flow transitions from port 3 P to port 2 A and from port 4 B to port 1 T. Conversely, when coil B is energized, the flow shifts from port 3 to port 4 and from port 2 to port 1. The valve's solenoid tube assembly is engineered for fatigue resistance, rated for service up to 5000 psi (350 bar), ensuring durability in demanding applications. This model requires no minimum hydraulic pressure for operation due to its direct actuation design. It incorporates a wet armature configuration allowing the working fluid to cool the armature but also necessitates consideration of thermal breakdown in certain fluids over time. The valve supports a variety of coil termination and voltage options, enhancing adaptability across different systems. It boasts high efficiency through its unique magnetic design which maximizes spool actuating force per watt expended. The DNDCXYV212N features interchangeable coils compatible with other Sun Series 1 solenoid products and can be mounted in either direction. Coil connector options offer protection ratings up to IP69K, with additional weatherized coils available for enhanced environmental resistance. The floating style construction minimizes internal binding risks due to installation torque or machining variations. With a capacity of up to 5 gpm (20 L/min) and a typical response time of approximately 50 ms, this valve is suitable for applications requiring rapid switching frequency up to 15,000 cycles per hour. Its robust construction makes it an ideal choice for systems utilizing phosphate ester fluids when equipped with EPDM seals; however, these seals should not be exposed to petroleum-based substances.

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.
