The Sun Hydraulics DNDAXDN248 (DNDAXDN248) is a solenoid-operated, 4-way, 2-position cartridge valve designed for direct-acting, balanced spool directional control. Engineered for robust performance, the valve features a solenoid tube assembly that is fatigue-rated for service pressures up to 5000 psi (350 bar). It operates without requiring minimum hydraulic pressure and offers various manual override options, although manual override is not compatible with weatherized coils. The valve's manual control assemblies have a mechanical life expectancy of approximately 7,000 cycles and are equipped with detent mechanisms for temporary actuation in select models. For systems utilizing phosphate ester fluids, EPDM seals are available; however, these seals should not be exposed to petroleum-based substances as they may cause damage. The valve employs a wet armature design which allows the working fluid to absorb heat generated by the coil. This can impact performance in applications where the coil remains energized for extended periods, especially when using water-glycol mixtures that may degrade over time. A range of coil termination and voltage options are offered to meet specific needs, including models with surge protection capabilities. Coils are interchangeable with other Sun Series 1 products and can be mounted in either direction. The cartridge incorporates Sun's floating style construction to reduce internal binding risks due to installation torque or machining variations. With a capacity of 10 gpm (40 L/min) and a response time of approximately 50 ms, this valve is suitable for high-frequency switching up to 15,000 cycles per hour. The maximum allowable leakage at specified conditions is 10 in\u00b3/min (160 cc/min). The DNDAXDN248 fits into T31A cavities and requires an installation torque between 30-35 lbf ft (41-47 Nm).

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.
