The Sun Hydraulics DNCADAN948 (DNCADAN948) is a high-performance solenoid-operated, 4-way, 2-position cartridge valve engineered for precise hydraulic control. This direct-acting, balanced spool directional valve ensures a closed transition between positions to minimize oil loss during shifting, which is crucial in maintaining the efficiency of pilot control circuits. The valve's design allows port 3 to function as the inlet and port 1 as the tank outlet, supporting a flow capacity of up to 8 gpm (30 L/min) and a maximum operating pressure of 5000 psi (350 bar). The DNCADAN948 features a fatigue-rated solenoid tube assembly suitable for service at pressures up to 350 bar, ensuring durability and reliability under demanding conditions. It operates without needing a minimum hydraulic pressure, adding to its versatility in various applications. The wet armature design surrounding the armature with working fluid helps manage heat but requires consideration of fluid type due to potential breakdowns from prolonged heat exposure. This model incorporates advanced sealing options with EPDM seals specifically designed for systems using phosphate ester fluids; however, these seals are susceptible to damage when exposed to petroleum-based fluids. For electrical customization, this valve offers a range of coil termination and voltage options including models with surge protection and environmental shielding options like weatherized coils. Additionally, the DNCADAN948 benefits from Sun Hydraulics' floating style construction which minimizes internal parts binding due to installation torque or machining variations in the cavity/cartridge setup. The valve supports manual override functionalities and can switch up to 15,000 cycles per hour with typical response times around 50 ms. Its robust design is complemented by interchangeable coils that are compatible with other Sun Series 1 solenoid products, enhancing its adaptability for different system configurations.
