The Sun Hydraulics DNDATUN828 (DNDATUN828) is a solenoid-operated, 4-way, 2-position cartridge valve designed for direct-acting, balanced spool directional control. This robust component is engineered with a solenoid tube assembly that is fatigue-rated for service up to 5000 psi (350 bar), ensuring reliable performance under demanding conditions. The valve operates without requiring a minimum hydraulic pressure, making it versatile for various applications. It features multiple manual override options, though these are not compatible with weatherized coils. Models equipped with D or L control include a detent mechanism in the manual override intended for temporary actuation, with an estimated mechanical life of approximately 7,000 cycles. The DNDATUN828 utilizes a wet armature design where the working fluid surrounds the armature, which can affect performance if the coil is energized for extended periods, especially with certain fluids like water-glycol mixtures that may degrade over time. The valve offers numerous coil termination and voltage options, some including surge protection. Its high-efficiency solenoid delivers significant spool actuating force per watt expended, ensuring dependable valve shifting. This cartridge incorporates Sun's floating style construction to reduce potential internal binding due to installation torque or cavity-cartridge machining variations. It fits into T31A cavities and belongs to Series 1 with a capacity of 10 gpm (40 L/min). The maximum operating pressure is rated at 5000 psi (350 bar), and it exhibits a typical response time of 50 ms. It can handle switching frequencies up to 15,000 cycles per hour and has a maximum leakage rate of 10 in\u00b3/min at 3000 psi (160 cc/min at 210 bar). The manual override requires a force of approximately 5 lbs at specific port pressures and features a stroke length of .10 inches (2.5 mm). The product's compact design includes a solenoid tube diameter of .75 inches (19 mm) and weighs .60 lb (.30 kg).

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.
