The Sun Hydraulics DNDAXRNHN24AB (DNDAXRNHN24AB) is a solenoid-operated 4-way, 2-position cartridge valve designed for direct-acting, balanced spool directional control. Engineered for robust applications, it features a fatigue-rated solenoid tube assembly suitable for up to 5000 psi (350 bar) service. This valve operates without the need for minimum hydraulic pressure, making it versatile in various systems. It offers multiple manual override options, although these are not compatible with weatherized coils. The manual control assembly has a mechanical life expectancy of approximately 7,000 cycles and requires specific force and stroke parameters for operation. The DNDAXRNHN24AB utilizes a wet armature design, which allows the working fluid to surround the armature and manage heat dissipation from the coil. This feature is crucial when using fluids that may degrade at high temperatures over time. A variety of coil termination and voltage options are available, enhancing flexibility in different operational environments. The solenoid's magnetic design ensures high efficiency with reliable valve shifting capabilities. This model incorporates Sun's floating style construction to minimize internal part binding due to installation torque or machining variations. It fits into cavity T-31A and belongs to Series 1 with a capacity of 10 gpm (40 L/min). The valve has an impressive response time of approximately 50 ms and can handle switching frequencies up to 15,000 cycles per hour. Seal integrity is maintained with Viton seal kits designed specifically for this cartridge and its coil components. Overall, the DNDAXRNHN24AB is engineered for reliability and efficiency in demanding hydraulic applications where precise directional control is essential.

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.
