The Sun Hydraulics DNCADLV648 (DNCADLV648) is a high-performance solenoid-operated, 4-way, 2-position cartridge valve designed for rigorous hydraulic applications. It features a direct-acting, balanced spool with closed transition between positions, which minimizes oil loss during shifting\u2014an essential feature for maintaining efficiency in pilot control circuits. The valve is engineered for a capacity of 8 gpm/30 L/min using port 3 as the inlet and port 1 as the tank. The design allows reverse flow although it is not recommended due to potential performance variations. This model incorporates a fatigue-rated solenoid tube assembly capable of handling up to 5000 psi (350 bar), making it suitable for demanding environments. Its direct actuation does not require minimum hydraulic pressure, enhancing its operational flexibility. Notably, cartridges with EPDM seals are specifically made for systems using phosphate ester fluids; however, they are vulnerable to damage if exposed to petroleum-based substances. The DNCADLV648 employs a wet armature design where the working fluid surrounds the armature. This design consideration is vital as prolonged coil energization can lead to fluid breakdown, especially in water-glycol mixtures, affecting cartridge functionality. A variety of coil termination and voltage options are available to suit different requirements and environments, with specific models offering up to IP69K protection. Sun Hydraulics has equipped this valve with interchangeable coils compatible with other Series 1 solenoid products and features a unique magnetic design that enhances solenoid efficiency and reliability in valve shifting. The construction also includes Sun\u2019s floating style which reduces risks associated with internal parts binding due to installation issues or cavity/cartridge machining variations. Overall, the DNCADLV648 offers robust performance and versatility for hydraulic system applications requiring precise control and reliability under high-pressure conditions.
