The Sun Hydraulics DNDAXJV211 (DNDAXJV211) is a solenoid-operated, 4-way, 2-position cartridge valve designed for direct-acting, balanced spool directional control. This valve is engineered to operate at a maximum pressure of 5000 psi (350 bar) and does not require minimum hydraulic pressure for activation. It features a solenoid tube assembly that is fatigue-rated for high-pressure environments and offers various manual override options, including models without manual override capabilities. However, it is important to note that manual override functionality is incompatible with weatherized coils. The valve's detent mechanism in the manual override is intended for temporary actuation and has a mechanical life expectancy of approximately 7,000 cycles. This cartridge utilizes a wet armature design where the working fluid surrounds the armature, which can influence performance if the coil remains energized for extended periods. Fluids like water-glycol mixtures may degrade over time at these temperatures, potentially affecting functionality. The DNDAXJV211 provides multiple coil termination and voltage configurations with optional surge protection. Its unique magnetic design ensures high efficiency by delivering substantial spool actuating force per watt expended. The valve boasts a capacity of 10 gpm (40 L/min) and demonstrates typical response times of around 50 ms. It accommodates switching frequencies up to 15,000 cycles per hour and maintains minimal leakage under specified conditions. The solenoid tube diameter measures .75 inches (19 mm), while the valve's hex size is .78 inches (22.2 mm). Installation torque ranges between 30-35 lbf ft (41-47 Nm), ensuring secure mounting. Additional features include interchangeable coils compatible with other Sun Series 1 solenoid products and robust environmental protection options through various coil connector ratings up to IP69K. This cartridge incorporates Sun's floating style construction to reduce internal part binding due to excessive installation torque or machining variations in cavity/cartridge interfaces.
