The Sun Hydraulics DNDAXHN648 (DNDAXHN648) 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 demanding hydraulic applications. This valve operates without the need for minimum hydraulic pressure, offering flexibility in various systems. The DNDAXHN648 includes multiple manual override options; however, these are not compatible with weatherized coils. The manual control assembly has an estimated mechanical life of approximately 7,000 cycles when equipped with the D or L control detent mechanism. Notably, cartridges using EPDM seals are intended for phosphate ester fluid systems and may be compromised by petroleum-based fluids. This valve employs a wet armature design that allows the working fluid to surround the armature, which can influence performance if the coil is energized for extended periods. Various coil termination and voltage options enhance adaptability, with interchangeable coils compatible across Sun Series 1 solenoid products. Coil connectors are available with ratings up to IP69K for robust environmental protection. The DNDAXHN648 incorporates Sun's floating style construction to reduce internal part binding risks due to installation torque or machining variations. With a capacity of 10 gpm (40 L/min) and response time of approximately 50 ms, this cartridge is optimized for high efficiency and reliable valve shifting. It supports a maximum switching frequency of 15,000 cycles per hour and maintains minimal leakage at specified conditions. Installation requires specific torque values and comes with detailed seal kit options to ensure optimal performance in hydraulic systems.

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.
