The Sun Hydraulics DNCADBN512 (DNCADBN512) is a high-performance, solenoid-operated, 4-way, 2-position cartridge valve featuring a direct-acting, balanced spool with closed transition. This design notably minimizes oil loss during shifting, which is crucial in maintaining efficiency in pilot control circuits. The valve operates effectively with port 3 as the inlet and port 1 as the tank, though it allows for reverse flow under certain conditions. Engineered to handle a maximum operating pressure of 5000 psi (350 bar) and a flow capacity of up to 8 gpm (30 L/min), the DNCADBN512 ensures robust performance in demanding applications. It boasts a rapid response time of approximately 50 ms and maintains tight control over leakage with a maximum valve leakage rate at 110 SUS (24 cSt) being about 10 in\u00b3/min at 3000 psi. Additionally, this model can handle up to 15,000 switching cycles per hour. The solenoid tube assembly of this valve is fatigue rated for high-pressure service and incorporates a wet armature design where the working fluid surrounds the armature. This arrangement necessitates consideration of the fluid type used, as prolonged exposure to heat could degrade certain fluids like water-glycol mixtures. For versatility in application and installation, Sun Hydraulics offers a variety of coil termination and voltage options for this model, including configurations with surge protection. The coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. The DNCADBN512 also features IP69K-rated connector options for enhanced environmental protection. Incorporating Sun\u2019s unique floating style construction, the DNCADBN512 minimizes internal part binding due to variations in installation torque or cavity/cartridge machining discrepancies, ensuring reliable operation and longevity of the valve system. This model is particularly suited for systems using phosphate ester fluids when configured with EPDM seals but should avoid exposure to petroleum-based substances to prevent seal damage.
