The Sun Hydraulics DNDATUV2E12V (DNDATUV2E12V) is a solenoid-operated 4-way, 2-position cartridge valve designed for direct-acting, balanced spool directional control. This valve is engineered to operate under a maximum pressure of 5000 psi (350 bar) and features a fatigue-rated solenoid tube assembly, ensuring robust performance in demanding applications. Notably, the valve does not require a minimum hydraulic pressure for operation, making it versatile across various systems. It offers multiple manual override options, although these are incompatible with weatherized coils. The DNDATUV2E12V uses a wet armature design, where the working fluid surrounds the armature and absorbs heat from the coil. This design consideration is crucial for systems where the coil may be energized for extended periods, as certain fluids like water-glycol mixtures can degrade over time at elevated temperatures. The valve's solenoid exhibits high efficiency due to its unique magnetic design, providing reliable shifting with significant spool actuating force per watt expended. This model is compatible with interchangeable coils from Sun Series 1 solenoid products and accommodates various coil termination and voltage options. Coil connector choices support ratings up to IP69K for enhanced environmental protection. The valve's construction incorporates Sun's floating style to minimize internal binding risks due to installation torque or machining variations. Key specifications include a capacity of 10 gpm (40 L/min), typical response time of 50 ms, and maximum leakage of 10 in\u00b3/min at 3000 psi (160 cc/min at 210 bar). The valve can handle switching frequencies up to 15,000 cycles per hour and requires specific manual override forces depending on port pressure conditions. With a hex size of .78 inches (22.2 mm) and an installation torque range of 30-35 lbf ft (41-47 Nm), this cartridge weighs approximately .60 lb (.30 kg). Seal kits are available with Viton materials for enhanced durability in various fluid environments.
