The Sun Hydraulics DNDATTN524 (DNDATTN524) is a solenoid-operated, 4-way, 2-position cartridge valve featuring a direct-acting, balanced spool design. Engineered for high performance, this valve has a fatigue-rated solenoid tube assembly capable of handling up to 5000 psi (350 bar), ensuring robust operation without the need for minimum hydraulic pressure. It supports various manual override options, although it's important to note that weatherized coils are incompatible with manual override functionality. The D and L control models include a detent mechanism for temporary actuation with an estimated mechanical life of 7,000 cycles. This valve is suitable for systems using phosphate ester fluids when equipped with EPDM seals but should avoid petroleum-based fluids to prevent seal damage. The DNDATTN524 utilizes a wet armature design where working fluid surrounds the armature, potentially impacting function if the coil is energized continuously in certain fluid types like water-glycol mixtures. The solenoid's magnetic design offers high efficiency and reliable valve shifting by delivering substantial spool actuating force per Watt used. It accommodates various coil termination and voltage configurations with optional surge protection and interchangeable coils compatible with other Sun Series 1 products. This cartridge valve fits into cavity T31A and belongs to Series 1, offering a capacity of 10 gpm (40 L/min). It operates efficiently within its maximum pressure rating while maintaining typical response times around 50 ms. The valve\u2019s leakage rates are minimal at specified conditions, and it can handle switching frequencies up to 15,000 cycles per hour. Installation requires specific torque settings, ensuring optimal performance without internal part binding due to Sun's floating style construction. The model weighs approximately .60 lb (0.30 kg) and comes with Viton seal kits available for both 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.
