The Sun Hydraulics DNDAXNN812N (DNDAXNN812N) 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 operates without the need for minimum hydraulic pressure, making it versatile for various applications. It features a robust solenoid tube assembly rated for fatigue at 5000 psi (350 bar), ensuring durability under high-pressure conditions. The valve allows for multiple manual override options, although these are not compatible with weatherized coils. Equipped with a wet armature design, the valve's working fluid surrounds the armature and dissipates heat generated by the coil; however, caution is advised when using fluids like water-glycol mixtures that may degrade over time due to heat exposure. This model offers diverse coil termination and voltage configurations, including options with surge protection, and maintains compatibility with other Sun Series 1 solenoid products. With its unique magnetic design, the solenoid delivers high efficiency by producing significant spool actuating force per watt expended, ensuring reliable operation. The valve supports a flow capacity of 10 gpm (40 L/min) and can handle a maximum operating pressure of up to 5000 psi (350 bar). Its typical response time is around 50 ms with a maximum leakage rate of 10 in\u00b3/min at 3000 psi (160 cc/min at 210 bar). Additionally, it features a switching frequency of up to 15,000 cycles per hour. The Sun Hydraulics DNDAXNN812N incorporates floating style construction to minimize internal binding risks due to installation torque or machining variations. It requires an installation torque of 30-35 lbf ft (41-47 Nm) and has a manual override stroke of .10 inches (2.5 mm). The valve's compact design includes a hex size of .78 inches (22.2 mm) and weighs approximately .60 lb (.30 kg).

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.
