The Sun Hydraulics DNDCXCV748 (DNDCXCV748) is a direct acting, solenoid-operated, 4-way, 3-position spool valve designed for precise fluid control in hydraulic systems. This valve features a spring-centered neutral position and offers versatile flow configurations depending on coil activation. When coil A is energized, the flow path directs from port 3 P to port 2 A and from port 4 B to port 1 T. Conversely, energizing coil B redirects the flow from port 3 to port 4 and from port 2 to port 1. The solenoid tube assembly is engineered for high durability, with a fatigue rating suitable for service pressures up to 5000 psi (350 bar), ensuring reliable performance under demanding conditions. Notably, this valve operates without requiring a minimum hydraulic pressure due to its direct actuation design. In differential flow circuits, it is recommended that higher return flows are routed through port 2 A to port 1 T for optimal performance. Cartridges equipped with EPDM seals are compatible with phosphate ester fluids but should be protected from petroleum-based substances to avoid seal damage. The valve's wet armature design allows the working fluid to absorb heat generated by the coil; however, prolonged energization may cause fluid breakdown in certain mixtures like water-glycol. The DNDCXCV748 model includes various coil termination and voltage options, some featuring surge protection capabilities for enhanced operational flexibility. The efficient magnetic design of the solenoid delivers high actuating force per Watt consumed, contributing to dependable valve shifting. Coils are interchangeable across Sun Series 1 products and can be installed in either direction on the tube. Additionally, coil connectors offer protection ratings up to IP69K for robust environmental resistance. This model incorporates Sun's floating style construction to minimize internal binding risks due to installation torque or machining variations, supporting consistent functionality across 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.
