The Sun Hydraulics DNCALBN848 (DNCALBN848) is a high-performance, solenoid-operated, 4-way, 2-position cartridge valve designed for precise hydraulic control. This direct-acting, balanced spool directional valve features a closed transition between positions, which minimizes the loss of oil during shifting\u2014a critical feature for maintaining efficiency in pilot control circuits. With port 3 as the inlet and port 1 as the tank, the valve supports a flow capacity of 8 gpm (30 L/min) and can handle a maximum operating pressure of up to 5000 psi (350 bar). Designed for robust operation, the DNCALBN848's solenoid tube assembly is fatigue rated for high-pressure service. It does not require minimum hydraulic pressure for operation, making it versatile across various applications. The valve employs EPDM seals when configured for systems using phosphate ester fluids; however, these seals are susceptible to damage if exposed to petroleum-based fluids. The DNCALBN848 incorporates a wet armature design where the working fluid surrounds the armature. This design consideration is crucial when the coil is energized over extended periods since some fluids may degrade under sustained heat exposure. The product also boasts a variety of coil termination and voltage options that enhance its adaptability and performance in different environments. Sun Hydraulics has equipped this model with interchangeable coils compatible with other Sun Series 1 solenoid products, adding to its flexibility in use and maintenance. The valve's innovative magnetic design enhances efficiency by maximizing spool actuating force per watt expended, ensuring reliable shifting even under demanding conditions. Additionally, this model benefits from Sun\u2019s floating style construction which reduces risks associated with internal parts binding due to installation torque or machining variations in cavity/cartridge setups. With features like an IP69K rating option for coil connectors and additional weatherized coils available for enhanced environmental protection, the DNCALBN848 is engineered to meet stringent operational demands reliably.
