The Sun Hydraulics DNDAXJV748 (DNDAXJV748) is a solenoid-operated 4-way, 2-position cartridge valve designed for direct-acting, balanced spool directional control. This valve features a robust solenoid tube assembly that is fatigue-rated for service up to 5000 psi (350 bar), ensuring reliable performance under high-pressure conditions. It operates without requiring a minimum hydraulic pressure, making it versatile for various applications. The valve offers several manual override options, although weatherized coils are not compatible with these overrides. Models with D or L control include a detent mechanism in the manual override intended for temporary actuation and have an approximate mechanical life expectancy of 7,000 cycles. The cartridge is suitable for systems using phosphate ester fluids when equipped with EPDM seals; exposure to petroleum-based fluids can damage these seals. Utilizing a wet armature design, this valve's working fluid surrounds the armature and absorbs heat from the coil, which may affect certain fluids like water-glycol mixtures over time. The solenoid's magnetic design ensures high efficiency, providing substantial spool actuating force per watt used and reliable shifting of the valve. The DNDAXJV748 features interchangeable coils compatible with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. Coil connector options offer ratings up to IP69K for enhanced environmental protection. The Sun floating style construction minimizes internal part binding due to excessive installation torque or cavity machining variations. Technical specifications include a T31A cavity, Series 1 classification, a capacity of 10 gpm (40 L/min), and response time typically around 50 ms. It supports a maximum switching frequency of 15,000 cycles/hour and requires specific manual override forces depending on pressure conditions. The valve\u2019s compact design includes dimensions such as a .75-inch solenoid tube diameter and .78-inch hex size, with installation torque ranging from 30 to 35 lbf ft (41 to 47 Nm).
