The Sun Hydraulics DNDAXLN628 (DNDAXLN628) is a solenoid-operated 4-way, 2-position cartridge valve designed for direct-acting, balanced spool directional control. This valve is engineered with a fatigue-rated solenoid tube assembly capable of handling up to 5000 psi (350 bar), making it suitable for high-pressure applications. It operates without the need for minimum hydraulic pressure, providing versatility across various systems. The DNDAXLN628 offers multiple manual override options, although these are incompatible with weatherized coils. For models featuring the D or L control, the detent mechanism in the manual override is intended for temporary actuation and has a mechanical life expectancy of approximately 7,000 cycles. The valve's wet armature design allows working fluid to surround the armature, which helps dissipate heat generated by the coil but may affect certain fluids like water-glycol mixtures over long periods. A range of coil termination and voltage options is available, including those with surge protection, ensuring adaptability to different electrical requirements. The solenoid's magnetic design enhances efficiency by maximizing spool actuating force per Watt expended. Coils are interchangeable with other Sun Series 1 products and can be mounted in either direction. With a capacity of 10 gpm (40 L/min) and a typical response time of 50 ms, this cartridge valve delivers reliable performance under demanding conditions. It features Sun's floating style construction to reduce internal binding risks from installation torque or machining variations. The DNDAXLN628 supports a maximum switching frequency of 15,000 cycles per hour and maintains minimal leakage at high pressure levels. For systems utilizing phosphate ester fluids, EPDM seals are recommended to prevent damage from petroleum-based substances.

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.
