The Sun Hydraulics DNDAXSN912N (DNDAXSN912N) is a solenoid-operated, 4-way, 2-position cartridge valve designed for precise directional control in hydraulic systems. This direct-acting, balanced spool directional valve features a robust solenoid tube assembly, fatigue-rated for service up to 5000 psi (350 bar), ensuring reliability in demanding applications. It operates without the need for minimum hydraulic pressure and offers multiple manual override options, though these are not compatible with weatherized coils. The valve's design incorporates a wet armature, which can impact fluid stability if the coil is energized for extended periods. This makes it important to consider fluid types that can withstand such conditions. The DNDAXSN912N boasts high efficiency due to its unique magnetic design, providing significant spool actuating force per watt expended and ensuring dependable valve shifting. It supports various coil termination and voltage configurations, including options with surge protection and IP69K-rated connectors for enhanced environmental resilience. The cartridge utilizes Sun's floating style construction to minimize internal binding risks from installation torque or machining variations. With a capacity of 10 gpm (40 L/min) and maximum leakage of 10 in\u00b3/min at 3000 psi (160 cc/min at 210 bar), this model is suitable for high-frequency switching applications up to 15,000 cycles per hour. It requires a manual override force of approximately 5 lbs at 1000 psi and features a compact design with dimensions including a solenoid tube diameter of .75 inches (19 mm) and installation torque between 30-35 lbf ft (41-47 Nm). The DNDAXSN912N is ideal for hydraulic systems needing reliable directional control with flexible configuration options.

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.
