The Sun Hydraulics DNDATDN828 (DNDATDN828) is a solenoid-operated, 4-way, 2-position cartridge valve featuring a direct-acting, balanced spool design. It is engineered for high-performance applications with a fatigue-rated solenoid tube assembly suitable for up to 5000 psi (350 bar) service. This valve operates without requiring minimum hydraulic pressure and offers several manual override options, though these are not compatible with weatherized coils. Models with D or L control include a detent mechanism in the manual override designed for temporary actuation, boasting a mechanical life expectancy of approximately 7,000 cycles. The DNDATDN828 utilizes EPDM seals for systems using phosphate ester fluids; use with petroleum-based fluids will damage the seals. The wet armature design allows working fluid to surround the armature, exposing it to coil heat\u2014an important consideration for long-term coil energization as certain fluids may degrade and affect functionality over time. The solenoid's magnetic design enhances efficiency, providing high spool actuating force per watt expended and ensuring reliable valve shifting. This cartridge can handle up to 10 gpm (40 L/min) capacity and features interchangeable coils compatible with other Sun Series 1 products. Coil connector options offer ratings up to IP69K for robust environmental protection. The valve incorporates Sun's floating style construction to reduce internal part binding risks due to installation torque or machining variations. With a response time of about 50 ms and maximum leakage at set conditions of 10 in\u00b3/min (160 cc/min), this model supports high switching frequency up to 15,000 cycles/hr. It requires specific torque settings for installation and comes equipped with Viton seal kits for both cartridge and coil components.

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.
