The Sun Hydraulics DNDAXSN528 (DNDAXSN528) is a solenoid-operated, 4-way, 2-position cartridge valve designed for direct-acting, balanced spool directional control. This versatile valve is capable of operating at a maximum pressure of 5000 psi (350 bar) and can handle a flow capacity of 10 gpm (40 L/min). It features a fatigue-rated solenoid tube assembly designed for high-pressure service without requiring any minimum hydraulic pressure for operation. The valve offers multiple manual override options, although these are incompatible with weatherized coils. Notably, the manual override mechanism on models with D or L control is intended for temporary actuation and has an estimated mechanical life of approximately 7,000 cycles. The product is constructed with EPDM seals suitable for use in systems with phosphate ester fluids; however, these seals are not compatible with petroleum-based fluids. The wet armature design improves operational efficiency by exposing the armature to the working fluid and heat generated by the coil. This design consideration is crucial when using fluids like water-glycol mixtures that can degrade at elevated temperatures over time. The Sun Hydraulics DNDAXSN528 offers various coil termination and voltage options including surge protection, allowing it to be adapted to different electrical configurations. Coils are interchangeable within the Sun Series 1 solenoid products line and can be mounted in either direction on the tube. The valve's unique magnetic design enhances efficiency by providing high spool actuating force per watt expended, ensuring reliable performance. Additionally, coil connector options provide ratings up to IP69K for robust environmental protection. The cartridge employs floating style construction to minimize internal binding risks due to installation torque or machining variations in cavity/cartridge interfaces.

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.
