The Sun Hydraulics DNDAXEV828 (DNDAXEV828) is a solenoid-operated 4-way, 2-position cartridge valve designed for direct-acting, balanced spool directional control. This robust valve is engineered for high performance with a fatigue-rated solenoid tube assembly capable of handling up to 5000 psi (350 bar) service pressure, making it suitable for demanding hydraulic applications. It operates without the need for a minimum hydraulic pressure, offering flexibility in various systems. The valve features multiple manual override options, although these are not compatible with weatherized coils. The detent mechanism in models equipped with D or L controls provides temporary actuation with an estimated mechanical life of around 7,000 cycles. To ensure compatibility with different fluids, cartridges fitted with EPDM seals are recommended for use with phosphate ester fluids only, as petroleum-based substances can damage the seals. The DNDAXEV828 utilizes a wet armature design where the working fluid surrounds the armature and absorbs heat generated by the coil. This design consideration is crucial as certain fluids may degrade over time due to prolonged exposure to heat. A variety of coil termination and voltage options are available, providing versatility and surge protection if needed. The solenoid's unique magnetic design ensures high efficiency and reliable valve shifting by maximizing spool actuating force per watt expended. This model incorporates Sun's floating style construction to minimize internal part binding due to installation torque or machining variations in cavity/cartridge applications. It has a Cavity T-31A configuration and belongs to Series 1, offering a capacity of 10 gpm (40 L/min) and response time typically around 50 ms. With interchangeable coils compatible across other Sun Series 1 products and IP69K-rated connector options, this valve provides comprehensive environmental protection and adaptability in installation orientations.

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.
