The Sun Hydraulics DNDATXN828 (DNDATXN828) is a solenoid-operated, 4-way, 2-position cartridge valve designed for direct-acting and balanced spool directional control. It features a fatigue-rated solenoid tube assembly capable of handling pressures up to 5000 psi (350 bar), making it suitable for demanding hydraulic applications. This valve does not require a minimum hydraulic pressure for operation and offers several manual override options, though manual override is incompatible with weatherized coils. The D, L, and T manual control assemblies provide temporary actuation with a mechanical life expectancy of approximately 7,000 cycles. This valve is compatible with systems using EPDM seals when operating with phosphate ester fluids; however, exposure to petroleum-based fluids can damage the seals. The DNDATXN828 utilizes a wet armature design, where the working fluid surrounds the armature and absorbs heat from the coil. This design consideration is essential for applications where the coil remains energized for extended periods since certain fluids may degrade under these conditions. A variety of coil termination and voltage options are available to enhance versatility, including surge protection features. The solenoid's advanced magnetic design ensures high efficiency by delivering significant spool actuating force per watt consumed. This cartridge valve incorporates Sun's floating style construction to minimize internal part binding due to installation torque or machining variations within the cavity/cartridge interface. It fits into a T-31A cavity and belongs to Series 1 with a flow capacity of 10 gpm (40 L/min). The valve demonstrates quick response times of approximately 50 ms and maintains low leakage rates at maximum operating pressures. With interchangeable coils that are compatible across Sun Series 1 solenoid products, users benefit from flexibility in assembly orientation and environmental protection options up to IP69K ratings.

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.
