The Sun Hydraulics DNDATTN224N (DNDATTN224N) is a solenoid-operated 4-way, 2-position cartridge valve known for its direct-acting, balanced spool directional capabilities. This valve is designed to operate without requiring a minimum hydraulic pressure, making it versatile for various applications. The solenoid tube assembly is rated for fatigue at 5000 psi (350 bar), ensuring reliability under high-pressure conditions. It features multiple manual override options, although these are incompatible with weatherized coils. The detent mechanism in models with D or L controls allows temporary actuation with a mechanical life expectancy of approximately 7,000 cycles. For systems utilizing phosphate ester fluids, cartridges equipped with EPDM seals are recommended to prevent seal damage from petroleum-based fluids. The valve employs a wet armature design where the working fluid surrounds the armature, which can be a consideration if the coil remains energized for extended periods due to potential fluid breakdown at high temperatures. A range of coil termination and voltage options are available, including surge protection capabilities. The unique magnetic design of the solenoid ensures high efficiency and reliable valve shifting by delivering significant spool actuating force per watt expended. This cartridge also incorporates Sun's floating style construction to reduce internal binding risks from excessive installation torque or machining variations in cavity-cartridge setups. It fits into T31A cavities and boasts a capacity of 10 gpm (40 L/min) with a maximum operating pressure of 5000 psi (350 bar). Typical response time is around 50 ms, and it supports switching frequencies up to 15,000 cycles per hour. The cartridge has minimal leakage rates and includes interchangeable coils compatible with other Sun Series 1 products that can be mounted in either direction.

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.
