The Sun Hydraulics DNCADLN828 (DNCADLN828) 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, significantly minimizing oil loss during shifting\u2014a critical feature in pilot control circuits. The valve operates efficiently with port 3 as the inlet and port 1 as the tank, while reverse flow is permissible but not recommended for optimal performance. Constructed to handle a maximum operating pressure of 5000 psi (350 bar) and a flow capacity of up to 8 gpm (30 L/min), the DNCADLN828 is robust and versatile for various hydraulic applications. The solenoid tube assembly is fatigue rated for high-pressure service, ensuring durability and long-term performance. Additionally, the valve requires no minimum hydraulic pressure for operation, enhancing its ease of use in different system configurations. The DNCADLN828 employs a wet armature design where the working fluid surrounds the armature. This design necessitates consideration of fluid properties as prolonged exposure to heat can lead to fluid breakdown, particularly with water-glycol mixtures. To accommodate different system requirements, cartridges with EPDM seals are available specifically for use with phosphate ester fluids; however, these are susceptible to damage if exposed to petroleum-based fluids. For further customization and adaptability across various applications, Sun Hydraulics offers an array of coil termination and voltage options for this model. These options include configurations with or without surge protection and coils that are interchangeable with other Sun Series 1 solenoid products. The coils can be mounted on the tube in either direction and connector options provide environmental protection ratings up to IP69K. Incorporating Sun\u2019s floating style construction minimizes internal part binding due to installation torque or machining variations in the cavity/cartridge setup. This feature ensures reliable operation and ease of maintenance across diverse industrial applications.
