The Sun Hydraulics DNDAXLN297 (DNDAXLN297) is a solenoid-operated, 4-way, 2-position cartridge valve designed for direct-acting, balanced spool directional control. This valve is engineered to operate at a maximum pressure of 5000 psi (350 bar) and features a fatigue-rated solenoid tube assembly for high-pressure service. It requires no minimum hydraulic pressure for operation and offers various manual override options, although the manual override is not compatible with weatherized coils. The valve's wet armature design allows the working fluid to surround the armature, which can be a consideration when the coil is energized for extended periods. It is important to note that cartridges with EPDM seals are suitable for phosphate ester fluids but may be damaged by petroleum-based fluids. The DNDAXLN297 also provides a high-efficiency solenoid with significant spool actuating force per watt expended, ensuring reliable valve shifting. This model accommodates interchangeable coils from other Sun Series 1 solenoid products and allows for flexible installation with coil connector options rated up to IP69K. With a capacity of 10 gpm (40 L/min), it ensures minimal internal part binding due to its floating style construction. The valve's typical response time is around 50 ms, and it supports a switching frequency of up to 15,000 cycles per hour. Installation specifications include a torque range of 30-35 lbf ft (41-47 Nm), and it features Viton seal kits available 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.
