The Sun Hydraulics DNDAXDN524 (DNDAXDN524) is a solenoid-operated, 4-way, 2-position cartridge valve known for its direct-acting and balanced spool design. This directional valve is engineered for high performance, with a solenoid tube assembly that is fatigue-rated for up to 5000 psi (350 bar), ensuring robust service life. It operates without the need for minimum hydraulic pressure, making it versatile across various applications. The valve offers multiple manual override options, although manual override is not compatible with weatherized coils. For models with D or L control, the detent mechanism in the manual override serves temporary actuation purposes and has a mechanical life expectancy of approximately 7,000 cycles. The cartridge is suitable for systems using phosphate ester fluids when equipped with EPDM seals; however, exposure to petroleum-based fluids can damage these seals. A key feature of this valve is its wet armature design, which allows the working fluid to surround the armature and manage heat from the coil efficiently. It\u2019s important to consider that fluids like water-glycol mixtures may break down over time due to heat exposure. Performance-wise, this valve boasts a capacity of 10 gpm (40 L/min) and maintains a maximum operating pressure of 5000 psi (350 bar). It features rapid response times around 50 ms and can handle switching frequencies up to 15,000 cycles per hour. The solenoid's magnetic design ensures high efficiency with significant spool actuating force per watt expended. The valve incorporates Sun's floating style construction to reduce internal binding risks due to installation torque or machining variations. With interchangeable coils compatible with other Sun Series 1 solenoid products and IP69K-rated coil connector options available, this valve offers flexibility in various environmental conditions.

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.
