The Sun Hydraulics DNDCXTV224 (DNDCXTV224) is a direct-acting, solenoid-operated, 4-way, 3-position spool valve designed for high-efficiency hydraulic applications. This valve is spring-centered to a neutral position and offers versatile flow control capabilities. When coil A is energized, the flow path is from port 3 P to port 2 A and from port 4 B to port 1 T. Conversely, energizing coil B directs 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 robust performance under demanding conditions without requiring minimum hydraulic pressure for operation. The DNDCXTV224 utilizes a wet armature design, where the working fluid surrounds the armature and absorbs heat generated by the coil. This feature necessitates consideration of fluid types used in prolonged operations as certain fluids may degrade over time due to heat exposure. The valve accommodates EPDM seals compatible with phosphate ester fluids but cautions against exposure to petroleum-based substances which can damage these seals. Sun Hydraulics offers various coil termination and voltage options, including surge protection configurations, enhancing its adaptability across different systems. The solenoid's magnetic design maximizes efficiency by delivering high spool actuating force per watt expended. Interchangeable coils with other Sun Series 1 products provide flexibility in installation, while options for weatherized coils ensure environmental protection up to IP69K ratings. This model supports a capacity of up to 5 gpm (20 L/min) with a typical response time of approximately 50 ms and maintains low leakage rates at maximum operating pressures. Designed with Sun's floating style construction, it minimizes internal binding risks due to installation torque or machining variations, ensuring reliable performance across diverse hydraulic 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.
