The Sun Hydraulics DNDCXTV648 (DNDCXTV648) is a direct acting, solenoid-operated, 4-way, 3-position spool valve designed for high-performance hydraulic systems. This valve is spring-centered to the neutral position and offers precise flow control by energizing either coil A or coil B. When coil A is activated, the flow transitions from port 3 P to port 2 A and from port 4 B to port 1 T. Conversely, when coil B is energized, the flow shifts from port 3 to port 4 and from port 2 to port 1. The solenoid tube assembly is robustly engineered for fatigue resistance up to a maximum operating pressure of 5000 psi (350 bar), ensuring durability in demanding applications. This valve features a wet armature design that enhances efficiency by surrounding the armature with working fluid, although it requires consideration of fluid compatibility due to potential heat exposure. It supports various coil termination and voltage options with surge protection capabilities, providing flexibility in integration. The high-efficiency solenoid design ensures reliable valve shifting with significant spool actuating force per watt expended. The DNDCXTV648 incorporates Sun's floating style construction to prevent internal binding due to installation torque variations. It offers a capacity of up to 5 gpm (20 L/min) and demonstrates rapid response times typically around 50 ms. Additionally, the valve minimizes leakage at specific viscosities and operates efficiently across a switching frequency of up to 15,000 cycles per hour. For optimal performance in differential flow circuits, directing higher return flow through specified ports is recommended. The valve also accommodates cartridges with EPDM seals for phosphate ester fluids while providing interchangeable coils compatible with other Sun Series 1 products. Its robust design and versatile configurations make it an ideal choice for various hydraulic applications requiring precision and reliability.

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.
