The Sun Hydraulics DNDAXXN848 (DNDAXXN848) is a solenoid-operated, 4-way, 2-position cartridge valve designed for direct-acting, balanced spool directional control. It features a fatigue-rated solenoid tube assembly capable of handling up to 5000 psi (350 bar), ensuring robust performance under high-pressure conditions. This valve operates without the need for minimum hydraulic pressure and offers various manual override options, although these are not compatible with weatherized coils. The direct actuation mechanism provides reliable operation with a mechanical life expectancy of around 7,000 cycles for models equipped with D or L controls. Designed with a wet armature, the valve's working fluid surrounds the armature and dissipates heat generated by the coil\u2014a consideration for systems where the coil remains energized for extended periods. Compatibility with EPDM seals makes it suitable for use in phosphate ester fluid systems, while exposure to petroleum-based fluids should be avoided to prevent seal damage. The valve supports multiple coil termination and voltage options, including those with surge protection, enhancing its adaptability across different applications. The solenoid's efficient magnetic design ensures high spool actuating force per watt expended, promoting dependable valve shifting. Coils are interchangeable within Sun Series 1 products and can be mounted in either direction on the tube. With coil connector options rated up to IP69K, this model can withstand harsh environmental conditions when paired with appropriate weatherized coils and kits. Incorporating Sun's floating style construction minimizes internal part binding due to excessive installation torque or machining variations in cavity/cartridge interfaces. It fits into a T-31A cavity and is part of Series 1 valves with a capacity of 10 gpm (40 L/min). The DNDAXXN848 model has a typical response time of 50 ms and can handle switching frequencies up to 15,000 cycles per hour while maintaining low leakage rates at specified viscosities and pressures.
