The Sun Hydraulics DNDCXYV299 (DNDCXYV299) is a direct-acting, solenoid-operated, 4-way, 3-position spool valve designed for efficient hydraulic flow control. This valve is spring-centered to maintain a neutral position and features two operational modes based on coil activation. When coil A is energized, the flow is directed from port 3 P to port 2 A and from port 4 B to port 1 T. Conversely, energizing coil B channels the flow from port 3 to port 4 and from port 2 to port 1. The solenoid tube assembly is rated for fatigue at pressures up to 5000 psi (350 bar), ensuring robust performance in demanding applications without requiring minimum hydraulic pressure for operation. This valve's design incorporates a wet armature system, where the working fluid surrounds the armature and absorbs heat generated by the coil. This feature is particularly relevant if the coil remains energized for extended periods, as certain fluids may degrade over time due to heat exposure. The DNDCXYV299 offers various coil termination and voltage options, including surge protection capabilities, enhancing its adaptability across different configurations. The high-efficiency solenoid design delivers significant spool actuating force per watt consumed, ensuring reliable valve shifting even under challenging conditions. Compatible with other Sun Series 1 solenoid products, coils can be mounted in either direction on the tube. The valve also supports coil connector options with ratings up to IP69K for enhanced environmental protection. Featuring Sun's floating style construction minimizes potential internal part binding due to excessive installation torque or machining variations within the cavity or cartridge. With a capacity of up to 5 gpm (20 L/min) and a typical response time of 50 ms, this valve is suitable for applications requiring precise control and quick response times. Additionally, it boasts a maximum leakage of only 10 in\u00b3/min at 3000 psi (160 cc/min at 210 bar), making it an efficient choice for various hydraulic systems.

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.
