The Sun Hydraulics DNDCXBV297 (DNDCXBV297) 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 and allows for versatile flow configurations when either coil A or coil B is energized. Specifically, energizing coil A directs flow from port 3 P to port 2 A and from port 4 B to port 1 T, while energizing coil B redirects flow from port 3 to port 4 and from port 2 to port 1. The solenoid tube assembly is engineered for fatigue resistance at pressures up to 5000 psi (350 bar), ensuring durability in demanding environments. This valve does not require a minimum hydraulic pressure for operation, making it suitable for various hydraulic systems. It features a wet armature design that immerses the armature in working fluid, which can impact performance if the coil remains energized for extended periods. This design consideration is crucial when using fluids prone to breakdown under heat exposure, such as water-glycol mixtures. The DNDCXBV297 offers multiple coil termination and voltage options with potential surge protection capabilities. Its high-efficiency solenoid design provides reliable spool actuation with minimal energy consumption. Coils are interchangeable with other Sun Series 1 products and support mounting in either direction. For added protection against environmental factors, weatherized coils and kits are available. With a capacity of up to 5 gpm (20 L/min) and a maximum valve leakage of 10 in\u00b3/min at 3000 psi (160 cc/min at 210 bar), this valve supports high-frequency switching up to 15,000 cycles per hour. It incorporates Sun's floating style construction to minimize internal binding risks due to installation variations or machining discrepancies. The DNDCXBV297 is compatible with Viton seal kits for both cartridge and coil applications, ensuring optimal performance across different operating 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.
