The Sun Hydraulics DNDAXSNHN24AB (DNDAXSNHN24AB) is a solenoid-operated, 4-way, 2-position cartridge valve designed for direct-acting and balanced spool directional control applications. This cartridge valve is engineered to operate at a maximum pressure of 5000 psi (350 bar) and features a fatigue-rated solenoid tube assembly for robust service. It requires no minimum hydraulic pressure to function and offers several manual override options, including models with temporary actuation detents. The valve incorporates EPDM seals suitable for phosphate ester fluid systems, although exposure to petroleum-based fluids can damage these seals. The wet armature design allows the working fluid to cool the armature, though prolonged coil energization may cause certain fluids to degrade over time. This model provides high efficiency due to its unique magnetic design, ensuring reliable spool actuation with minimal energy expenditure. Coils are versatile and interchangeable with other Sun Series 1 solenoid products, allowing installation flexibility. The valve supports various coil termination and voltage configurations, some equipped with surge protection, and offers coil connectors rated up to IP69K for enhanced environmental resistance. The DNDAXSNHN24AB incorporates Sun's floating style construction to reduce internal part binding risks from excessive installation torque or cavity machining variations. It fits into a T-31A cavity and has a capacity of 10 gpm (40 L/min). With a typical response time of 50 ms and capable of handling switching frequencies up to 15,000 cycles per hour, this valve is designed for high-performance applications that demand precision and durability. The model weighs approximately 0.60 lb (0.30 kg) and requires specific installation torque settings between 30-35 lbf ft (41-47 Nm). For maintenance or replacement needs, Viton seal kits are available for both the cartridge and coil components.

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.
