The Sun Hydraulics DNCADJN628 (DNCADJN628) is a high-performance, solenoid-operated, 4-way, 2-position cartridge valve designed for precise hydraulic control in various applications. This direct-acting, balanced spool directional valve ensures a closed transition between positions, significantly minimizing oil loss during shifting which is crucial in maintaining the efficiency of pilot control circuits. It operates with a capacity based on port 3 as the inlet and port 1 as the tank, though it allows reverse flow; performance in this mode isn\u2019t guaranteed and is generally not recommended. The DNCADJN628 features a robust solenoid tube assembly that is fatigue rated for up to 5000 psi (350 bar), making it suitable for high-pressure applications. Its direct actuation design requires no minimum hydraulic pressure for operation, providing flexibility and reliability across various operational conditions. The valve incorporates EPDM seals specifically for use with phosphate ester fluids; however, these seals are susceptible to damage when exposed to petroleum-based fluids. One of the distinctive aspects of this model is its wet armature design. The working fluid surrounds the armature which can be exposed to heat generated by the coil if energized for extended periods. This could degrade certain fluid types like water-glycol mixtures over time. Additionally, Sun Hydraulics offers a variety of coil termination and voltage options for this model, enhancing its adaptability to different electrical systems while maintaining protection against surge impacts. The DNCADJN628 also features interchangeable coils with other Sun Series 1 solenoid products and supports installation flexibility due to its floating style construction which minimizes internal parts binding caused by excessive installation torque or cavity-cartridge machining variations. With a maximum operating pressure of 5000 psi and a flow capacity of up to 8 gpm (30 L/min), this valve is engineered to meet rigorous industrial demands while ensuring reliable performance and environmental resilience through optional weatherized coils and kits.
