The Sun Hydraulics DNDAXRN824 (DNDAXRN824) is a solenoid-operated 4-way, 2-position cartridge valve that functions as a direct-acting, balanced spool directional valve. It is designed to operate efficiently at a maximum operating pressure of 5000 psi (350 bar) without the need for any minimum hydraulic pressure. The solenoid tube assembly is fatigue-rated for high-pressure service, ensuring durability and reliability in demanding applications. This model offers several manual override options, although not all are compatible with weatherized coils. The detent mechanism on models with D or L control is intended for temporary actuation with an approximate mechanical life expectancy of 7,000 cycles. This valve features EPDM seals suitable for phosphate ester fluids, but they must be protected from petroleum-based substances to prevent damage. Its wet armature design allows the working fluid to cool the armature while being exposed to coil-generated heat, which could affect certain fluids over time. The DNDAXRN824 boasts high efficiency due to its unique magnetic solenoid design that provides significant spool actuating force per watt used, ensuring reliable valve shifting. Coils are interchangeable with other Series 1 solenoid products and can be mounted bidirectionally on the tube. Various coil termination and voltage options are available, including those with surge protection and IP69K-rated connectors for enhanced environmental protection. The valve incorporates Sun's floating style construction to reduce internal binding risks from installation torque or machining variations. With a capacity of 10 gpm (40 L/min), a typical response time of 50 ms, and a switching frequency of up to 15,000 cycles per hour, this cartridge valve is versatile for various hydraulic applications requiring precise control and robustness.

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.
