The Sun Hydraulics DNDATLN624N (DNDATLN624N) is a solenoid-operated 4-way, 2-position cartridge valve designed for direct-acting, balanced spool directional control. This valve is fatigue-rated for service up to 5000 psi (350 bar) and operates without the need for minimum hydraulic pressure. It features a wet armature design, allowing the working fluid to surround the armature and manage heat generated by the coil. This design is especially relevant when using water-glycol mixtures, as prolonged exposure to high temperatures can lead to varnish formation, affecting function. The valve's solenoid boasts a unique magnetic design for efficient operation with high spool actuating force per watt expended, ensuring reliable shifting. The DNDATLN624N offers several manual override options, including a detent mechanism in models with D or L control for temporary actuation. The mechanical life expectancy of these controls is approximately 7,000 cycles. Cartridges equipped with EPDM seals are suitable for systems using phosphate ester fluids but should avoid petroleum-based substances to prevent seal damage. This model provides versatile coil termination and voltage configurations, some of which include surge protection capabilities. Coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. Additionally, connector options offer protection ratings up to IP69K for enhanced environmental resilience. With a capacity of 10 gpm (40 L/min) and a maximum valve leakage of 10 in\u00b3/min at 3000 psi (160 cc/min at 210 bar), this cartridge supports a switching frequency of up to 15,000 cycles/hr. The valve features Sun's floating style construction to minimize internal binding risks due to excessive installation torque or machining variations.

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.
