The Sun Hydraulics DNDAXLN928 (DNDAXLN928) is a solenoid-operated, 4-way, 2-position cartridge valve designed for direct-acting and balanced spool directional control. Built for durability, the solenoid tube assembly is rated for fatigue at 5000 psi (350 bar) service, ensuring reliable performance in demanding applications. This valve operates without the need for minimum hydraulic pressure and comes with various manual override options, though compatibility with weatherized coils should be noted. The manual override's detent mechanism on models equipped with D or L control is intended for temporary actuation and has a mechanical life expectancy of approximately 7,000 cycles. The valve's design incorporates a wet armature system where the working fluid surrounds the armature, which can affect fluid stability over prolonged coil energization due to heat exposure. It supports various coil termination and voltage options, enhancing its adaptability to different systems. The high-efficiency solenoid design provides significant actuating force per watt, promoting reliable valve shifting. This cartridge features Sun's floating style construction to reduce internal part binding from installation torque or machining variations. It fits into a T-31A cavity and belongs to Series 1 with a capacity of up to 10 gpm (40 L/min). The maximum operating pressure is set at 5000 psi (350 bar), with a typical response time of 50 ms. It boasts a switching frequency of up to 15,000 cycles per hour and minimal valve leakage at defined conditions. For maintenance or customization needs, Viton seal kits are available for both the cartridge and coil components. The compact design includes specifications such as a solenoid tube diameter of .75 inches (19 mm) and an installation torque range between 30-35 lbf ft (41-47 Nm), making it versatile for various hydraulic 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.
