The Sun Hydraulics DNDATTN724N (DNDATTN724N) is a robust solenoid-operated 4-way, 2-position cartridge valve designed for direct-acting, balanced spool directional control. It features a solenoid tube assembly that is fatigue-rated for service up to 5000 psi (350 bar), ensuring durability and reliability in high-pressure applications. This valve operates without the need for minimum hydraulic pressure, making it versatile in various systems. The DNDATTN724N offers several manual override options, although it's important to note that manual override functionality is incompatible with weatherized coils. Models equipped with the D or L control have a detent mechanism intended for temporary actuation and have a mechanical life expectancy of approximately 7,000 cycles. The valve uses EPDM seals suitable for systems utilizing phosphate ester fluids but should not be exposed to petroleum-based fluids as they can damage the seals. Its wet armature design allows the working fluid to surround the armature, which can influence performance if the coil remains energized for extended periods due to heat exposure affecting certain fluids like water-glycol mixtures. A variety of coil termination and voltage options are available with or without surge protection, enhancing its adaptability. The DNDATTN724N incorporates Sun's unique floating style construction to minimize binding risks from excessive installation torque or machining variations. It has a cavity T31A series 1 capacity of 10 gpm (40 L/min) and offers high efficiency due to its magnetic design, producing reliable valve shifting with minimal energy expenditure. Coil connectors are rated up to IP69K, providing excellent environmental protection. The valve supports interchangeable coils with other Sun Series 1 products and offers flexibility in installation orientation.

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.
