The Sun Hydraulics DNDAXRN828 (DNDAXRN828) is a solenoid-operated 4-way, 2-position cartridge valve designed for direct-acting, balanced spool directional control. This valve features a fatigue-rated solenoid tube assembly suitable for up to 5000 psi (350 bar) service, ensuring robust performance under high-pressure conditions. It operates without requiring minimum hydraulic pressure, making it versatile for various applications. The cartridge offers multiple manual override options, though manual overrides are incompatible with weatherized coils. Models with D or L control include a detent mechanism in the manual override for temporary actuation, with an estimated mechanical life of approximately 7,000 cycles. The valve is compatible with EPDM seals for use with phosphate ester fluids; however, these seals can be damaged by petroleum-based substances. A wet armature design allows the working fluid to surround the armature and absorb heat from the coil, which could affect certain fluids like water-glycol mixtures over extended periods. The valve accommodates various coil termination and voltage options, including models with surge protection. A key feature is its high-efficiency solenoid design that provides substantial spool actuating force per watt expended, ensuring reliable shifting of the valve. Coils are interchangeable within Sun Series 1 solenoids and can be mounted in any direction on the tube. Coil connectors support ratings up to IP69K for enhanced protection against environmental factors. This cartridge incorporates Sun's floating style construction to reduce internal binding risks due to installation torque or machining variations. It fits into cavity T-31A and has a flow capacity of 10 gpm (40 L/min), with a typical response time of 50 ms and maximum leakage at 110 SUS of 10 in\u00b3/min at 3000 psi (160 cc/min at 210 bar). The valve supports switching frequencies up to 15,000 cycles/hour and requires specific torque settings for installation.

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.
