The Sun Hydraulics DNCADSN612N (DNCADSN612N) is a high-performance, solenoid-operated, 4-way, 2-position cartridge valve designed for precise control in hydraulic systems. This direct-acting, balanced spool directional valve features a closed transition between positions, which significantly minimizes oil loss during shifting\u2014a crucial feature in pilot control circuits where maintaining fluid integrity is essential. The DNCADSN612N operates effectively with port 3 as the inlet and port 1 as the tank outlet, ensuring reliable performance under specified conditions. However, while reverse flow through the valve is possible, optimal performance under this condition is not assured and generally not recommended. The valve's solenoid tube assembly is robustly built to withstand up to 5000 psi (350 bar), making it suitable for high-pressure applications. Notably, this model requires no minimum hydraulic pressure to function and features an EPDM seal configuration suitable for phosphate ester fluids; however, exposure to petroleum-based substances should be avoided to prevent seal damage. This model also incorporates a wet armature design where the working fluid surrounds the armature\u2014important for applications where the coil may be energized continuously. The DNCADSN612N supports various coil termination and voltage options and offers interchangeable coils with other Sun Series 1 solenoid products. The unique magnetic design of the solenoid ensures efficient operation by generating a high spool actuating force per watt expended. Additional features include IP69K-rated coil connector options for enhanced environmental protection and Sun\u2019s floating style construction that minimizes internal parts binding. This valve provides a flow capacity of 8 gpm (30 L/min) at a maximum operating pressure of 5000 psi (350 bar), with typical response times around 50 ms and maximum allowable leakage well-controlled at operational pressures.
