The Sun Hydraulics DNDAXJN812N (DNDAXJN812N) is a solenoid-operated 4-way, 2-position cartridge valve designed for direct-acting, balanced spool directional control. It is engineered to handle up to 5000 psi (350 bar) service pressure and does not require minimum hydraulic pressure for operation. This model offers several manual override options, although weatherized coils are incompatible with manual override functionality. The valve features a wet armature design, which allows the working fluid to surround the armature and absorb heat from the coil, potentially impacting long-term performance in certain fluids like water-glycol mixtures. It supports a variety of coil termination and voltage configurations, including surge protection options, and boasts a high-efficiency magnetic solenoid design that provides reliable shifting with minimal energy expenditure. The interchangeable coils are compatible with other Sun Series 1 solenoid products and can be mounted in either direction. Connector options offer protection ratings up to IP69K for enhanced environmental resistance. The valve's floating style construction minimizes internal binding risks due to installation torque or machining variations. It fits into a T31A cavity and has a flow capacity of 10 gpm (40 L/min). Typical response time is around 50 ms with maximum leakage at specified conditions being 10 in\u00b3/min (3000 psi). The valve supports a switching frequency of up to 15000 cycles per hour and requires approximately 5 lbs/1000 psi force for manual override actuation over a stroke length of .10 inches. The solenoid tube diameter is .75 inches, while the hex size is .78 inches; installation torque ranges from 30 to 35 lbf-ft. The model weighs approximately .60 lb and is available with Viton seal kits 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.
