The Sun Hydraulics DNDCXBV214N (DNDCXBV214N) is a direct-acting, solenoid-operated, 4-way, 3-position spool valve designed for precise hydraulic control. It features a spring-centered neutral position and operates without the need for minimum hydraulic pressure. When coil A is energized, the fluid flows 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's solenoid tube assembly is fatigue rated for service up to 5000 psi (350 bar), ensuring durability under high-pressure conditions. This valve is particularly suitable for differential flow circuits where higher return flow should be managed through specific ports. It incorporates EPDM seals compatible with phosphate ester fluids but may degrade if exposed to petroleum-based substances. The wet armature design allows the working fluid to manage heat dissipation but requires consideration of fluid breakdown over time in long-term energized states, especially with water-glycol mixtures. The DNDCXBV214N offers high efficiency through its unique magnetic solenoid design, maximizing spool actuating force while minimizing power consumption. It supports a wide range of coil termination and voltage options, including surge protection capabilities. Coils are interchangeable with other Sun Series 1 products and can be mounted in either direction on the tube. With a capacity of handling up to 5 gpm (20 L/min) and a typical response time of 50 ms, this valve is engineered for reliable performance in demanding applications. Its construction minimizes internal binding risks due to installation or machining variances, thanks to Sun's floating style design approach. The valve's compact dimensions include a solenoid tube diameter of .75 inches (19 mm) and a hex size of .78 inches (22.2 mm), requiring an installation torque between 30-35 lbf ft (41-47 Nm).

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.
