The Sun Hydraulics DNDAXXN824 (DNDAXXN824) is a solenoid-operated, 4-way, 2-position cartridge valve known for its direct-acting, balanced spool design. This directional valve is fatigue-rated for service up to 5000 psi (350 bar) and does not require a minimum hydraulic pressure to operate. It features a wet armature design that immerses the armature in the working fluid, which can affect performance if the coil is energized for prolonged periods. This model offers several manual override options, though compatibility with weatherized coils is limited. The manual control assembly has an estimated mechanical life of about 7,000 cycles and requires approximately 5 lbs of force per 1000 psi at Port 1 for operation. The DNDAXXN824 incorporates Sun's floating style construction to reduce internal part binding from installation torque or machining variations. It supports various coil termination and voltage configurations with surge protection options available. The valve's solenoid design ensures high efficiency by providing significant spool actuating force relative to energy consumption, thus ensuring reliable shifting. Coil interchangeability with other Sun Series 1 solenoid products allows flexible mounting directions and connector ratings up to IP69K for enhanced environmental protection. With a capacity of 10 gpm (40 L/min), this valve supports a maximum operating pressure of 5000 psi (350 bar), and typical response time is around 50 milliseconds. It can handle switching frequencies up to 15,000 cycles per hour with maximum leakage at specified conditions being minimal. The cartridge's seal kit utilizes Viton material suitable for systems using phosphate ester fluids but may degrade if exposed to petroleum-based substances. Its compact design includes a T31A cavity configuration and weighs approximately .60 lb (0.30 kg).

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.
