The Sun Hydraulics DNDATUN224N (DNDATUN224N) is a solenoid-operated, 4-way, 2-position cartridge valve renowned for its direct-acting, balanced spool design. This valve is fatigue-rated for service up to 5000 psi (350 bar) and operates without the need for minimum hydraulic pressure. It features multiple manual override options, though these are not compatible with weatherized coils. The manual control assembly on models with the D or L control includes a detent mechanism intended for temporary actuation and has an estimated mechanical life of approximately 7,000 cycles. The cartridge is suitable for use with phosphate ester fluids when equipped with EPDM seals, while petroleum-based fluids can damage these seals. The valve's wet armature design allows the working fluid to surround the armature, which can be significant if the coil remains energized over extended periods. This feature necessitates careful consideration of fluid types to prevent breakdown at high temperatures. The valve boasts a high-efficiency solenoid due to its unique magnetic design, offering reliable shifting through substantial spool actuating force per watt expended. It accommodates various coil termination and voltage options, including those with surge protection. The DNDATUN224N utilizes Sun's floating style construction to reduce internal part binding risks due to excessive installation torque or machining variations in cavity/cartridge construction. With a capacity of 10 gpm (40 L/min), response time of approximately 50 ms, and maximum leakage rate at specified conditions of 10 in\u00b3/min (160 cc/min), this model is designed for robust performance. Coil options are interchangeable within Sun Series 1 solenoid products and can be mounted bi-directionally on the tube. Additional weatherized coils provide enhanced environmental protection with connector ratings up to IP69K.

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.
