The Sun Hydraulics DNDAXYN812N (DNDAXYN812N) is a solenoid-operated, 4-way, 2-position cartridge valve designed for direct-acting, balanced spool directional control. This valve is engineered with a fatigue-rated solenoid tube assembly that can withstand up to 5000 psi (350 bar) service. It operates without the need for minimum hydraulic pressure, making it versatile for various applications. The cartridge offers several manual override options, although models with manual override are not compatible with weatherized coils. Notably, the manual control's detent mechanism is intended for temporary use and has an approximate mechanical life expectancy of 7,000 cycles. The valve is equipped with EPDM seals suitable for phosphate ester fluid systems; however, these seals are sensitive to petroleum-based fluids which can cause damage. Featuring a wet armature design, the working fluid surrounds the armature and might be affected by heat from prolonged coil energization. Special consideration should be given to fluids like water-glycol mixtures that could degrade under these conditions. A variety of coil termination and voltage configurations are available, offering high-efficiency solenoid performance due to its unique magnetic design. This results in reliable valve shifting with high spool actuating force per watt expended. Coils are interchangeable within Sun Series 1 products and can be mounted in either direction on the tube. The product also offers coil connector options rated up to IP69K for enhanced environmental protection. The valve utilizes Sun's floating style construction to reduce internal binding risks caused by excessive installation torque or machining variations in cavity/cartridge interfaces. It has a capacity of 10 gpm (40 L/min) and features a quick response time of approximately 50 ms. The maximum leakage rate at 110 SUS (24 cSt) is 10 in\u00b3/min at 3000 psi (160 cc/min at 210 bar), ensuring efficient operation across various applications.

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.
