The Sun Hydraulics DNDAXUN528 (DNDAXUN528) is a solenoid-operated 4-way, 2-position cartridge valve designed for direct-acting, balanced spool directional control. This versatile valve is fatigue rated for service up to 5000 psi (350 bar) and operates without the need for minimum hydraulic pressure. It features various manual override options, including models with no manual override, and offers temporary actuation detent mechanisms in certain configurations. The DNDAXUN528 is equipped with EPDM seals suitable for systems using phosphate ester fluids, while exposure to petroleum-based substances should be avoided to prevent seal damage. Employing a wet armature design, the valve's armature is immersed in working fluid which can affect performance if the coil remains energized over extended periods, particularly with water-glycol mixtures that may degrade into varnishes. The solenoid's efficient magnetic design ensures reliable valve shifting by delivering high spool actuating force per watt consumed. With interchangeable coils compatible across Sun Series 1 solenoid products, it provides flexibility in installation direction and coil termination options up to IP69K ratings for enhanced environmental protection. The floating style construction minimizes internal part binding due to installation torque or machining variations in cavity/cartridge interfaces. The DNDAXUN528 fits T-31A cavities, supports flow capacities of 10 gpm (40 L/min), and maintains maximum operating pressures of 5000 psi (350 bar). It features a typical response time of 50 ms and allows a switching frequency of up to 15000 cycles per hour with minimal leakage rates at specified conditions. Installation requires a torque range between 30-35 lbf.ft (41-47 Nm), while its compact design weighs just .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.
