The Sun Hydraulics DNDAXUV648 (DNDAXUV648) is a solenoid-operated 4-way, 2-position cartridge valve designed for direct acting, balanced spool directional control. It features a fatigue-rated solenoid tube assembly capable of withstanding up to 5000 psi (350 bar), making it suitable for high-pressure hydraulic systems. This cartridge valve operates without the need for minimum hydraulic pressure and offers various manual override options, although these are not compatible with weatherized coils. The manual control assembly has an estimated mechanical life of around 7,000 cycles when equipped with the D or L control detent mechanism. The valve incorporates a wet armature design, where the working fluid surrounds the armature and is exposed to coil-generated heat, which can affect certain fluids like water-glycol mixtures over time. It supports a wide range of coil termination and voltage options, some with surge protection, and offers interchangeable coils compatible with other Sun Series 1 solenoid products. Coil connectors can achieve ratings up to IP69K for enhanced environmental protection. This valve employs Sun's floating style construction to reduce internal part binding due to installation torque or machining variations. With a capacity of 10 gpm (40 L/min) and a maximum operating pressure of 5000 psi (350 bar), it provides reliable performance with typical response times around 50 ms and maximum leakage rates at specified conditions. The valve's hex size measures .78 inches (22.2 mm) with an installation torque requirement of 30-35 lbf ft (41-47 Nm). It also includes Viton seal kits for both cartridge and coil assemblies, ensuring compatibility with various hydraulic fluids while maintaining durability in demanding applications.

This solenoid-operated 4-way, 2-position cartridge is a direct-acting, balanced spool directional valve.
- 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.
- This cartridge has several manual override choices, including no manual override. See the CONFIGURATION section. Please note: Manual override functionality is not compatible with weatherized coils.
- On models equipped with the D or L control, the detent mechanism in the manual override is meant for temporary actuation. The D, L and T manual control assembly has a mechanical life expectancy of approximately 7,000 cycles.
- 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.
