The Sun Hydraulics DNDAXXV912N (DNDAXXV912N) is a solenoid-operated 4-way, 2-position cartridge valve designed for direct-acting, balanced spool directional control. This valve is engineered to handle a maximum operating pressure of 5000 psi (350 bar) and features a solenoid tube assembly that is fatigue-rated for high-pressure service. It operates without the need for minimum hydraulic pressure, making it versatile for various applications. The valve offers multiple manual override options, although compatibility with weatherized coils should be noted. For models with D or L controls, the manual override detent mechanism is intended for temporary actuation with an estimated mechanical life expectancy of around 7,000 cycles. This cartridge utilizes a wet armature design where working fluid surrounds the armature, which can affect performance if the coil remains energized over long durations. Specifically, water-glycol mixtures may degrade under heat exposure and form varnishes that impact functionality. The solenoid's unique magnetic design ensures high efficiency by delivering robust spool actuating force relative to power consumption. Interchangeable coils with other Sun Series 1 products provide flexibility in installation direction and termination options include ratings up to IP69K. The valve boasts a capacity of 10 gpm (40 L/min) and typical response time of 50 ms. It maintains minimal leakage at specified conditions and supports high switching frequency up to 15,000 cycles per hour. Installation requires specific torque settings to prevent internal part binding due to excessive force or machining variations. Available seal kits ensure compatibility with various fluids; however, cartridges using EPDM seals should avoid petroleum-based substances as they can cause damage. This product's construction incorporates Sun's floating style design principles to enhance reliability in diverse operational environments.

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.
