The Sun Hydraulics DNCADZN628 (DNCADZN628) is a high-performance, solenoid-operated, 4-way, 2-position cartridge valve designed for precise hydraulic fluid direction control in various applications. This direct-acting, balanced spool directional valve ensures a closed transition between positions, significantly minimizing oil loss during shifting\u2014a crucial feature in pilot control circuits. With a robust design that includes a fatigue-rated solenoid tube assembly for up to 5000 psi (350 bar) service, the DNCADZN628 operates effectively without requiring a minimum hydraulic pressure. Its capacity is optimized with port 3 as the inlet and port 1 as the tank, although reverse flow capabilities are present but not recommended for optimal performance. The valve's quick response time of approximately 50 ms and a maximum operating pressure of 5000 psi underscore its efficiency and reliability in demanding settings. The valve features EPDM seals configured specifically for use with phosphate ester fluids; however, these seals are susceptible to damage when exposed to petroleum-based fluids. Its wet armature design allows the working fluid to surround the armature, which could be a consideration if the coil remains energized over extended periods due to potential breakdowns in certain fluid types at elevated temperatures. For customization and adaptability across different systems, the DNCADZN628 offers various coil termination and voltage options, including models with surge protection. Coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. Additionally, environmental protection is enhanced through optional weatherized coils and kits. The construction incorporates Sun's floating style to minimize internal part binding due to installation torque or cavity/cartridge machining variations. With its comprehensive features and configurable options, this valve is an essential component for efficient hydraulic system management across multiple applications.
