The Sun Hydraulics DNDAMXV828 (DNDAMXV828) is a solenoid-operated, 4-way, 2-position cartridge valve designed for precise directional control in hydraulic systems. This direct-acting, balanced spool valve is notable for its robust solenoid tube assembly, which is fatigue-rated for service at pressures up to 5000 psi (350 bar). It operates without requiring a minimum hydraulic pressure, making it versatile for various applications. The valve features multiple manual override options, although these are not compatible with weatherized coils. Its design includes a wet armature that enhances efficiency by utilizing the working fluid to manage coil heat dissipation; however, this can affect certain fluids over time. The DNDAMXV828 allows for a wide range of coil termination and voltage configurations, including options with surge protection. It boasts high efficiency due to its magnetic design, providing reliable spool actuation with minimal energy expenditure. The interchangeable coils are compatible with other Sun Series 1 products and offer IP69K-rated connector options for enhanced environmental protection. Additionally, the floating style construction minimizes internal binding risks due to installation torque variations or machining discrepancies. With a capacity of 10 gpm (40 L/min) and a typical response time of 50 ms, this valve supports high-frequency switching up to 15,000 cycles per hour. Its manual override requires minimal force and stroke length for operation. The DNDAMXV828 is compact yet durable, weighing just .60 lb (.30 kg), and is easy to install with a specified torque range of 30-35 lbf ft (41-47 Nm). Seal kits are available in Viton material to ensure compatibility and longevity in various fluid conditions.

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.
