The Sun Hydraulics DNDATDN (DNDATDN) is a solenoid-operated, 4-way, 2-position cartridge valve that utilizes a direct-acting, balanced spool design. This valve is built for robust performance with a fatigue-rated solenoid tube assembly capable of handling up to 5000 psi (350 bar). It requires no minimum hydraulic pressure for operation and offers various manual override options, though weatherized coils are incompatible with these overrides. Notably, the manual control assembly has an approximate mechanical life expectancy of 7,000 cycles when equipped with D or L controls. The cartridge is suitable for systems using phosphate ester fluids but should avoid petroleum-based fluids to prevent seal damage. Its wet armature design enhances reliability by allowing working fluid to cool the coil, although this can be detrimental if the coil remains energized for long durations with certain fluid types like water-glycol mixtures. The DNDATDN features a high-efficiency solenoid that delivers significant spool actuating force per watt expended, ensuring dependable valve shifting. It supports interchangeable coils from other Sun Series 1 products and can be mounted in either direction on the tube. Coil connector options provide protection ratings up to IP69K, and additional weatherized coils are available for enhanced environmental protection. The valve's floating style construction reduces the risk of internal parts binding due to excessive installation torque or machining variations in cavity/cartridge interfaces. With a capacity of 10 gpm (40 L/min) and a response time of approximately 50 ms, this valve is designed for high-frequency switching at up to 15,000 cycles per hour. It has specific installation requirements including a torque specification of 30 - 35 lbf ft (41 - 47 Nm) and uses Viton seals with part numbers available for both cartridge and coil applications.

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.
