The Sun Hydraulics DNCADCN912N (DNCADCN912N) is a solenoid-operated, 4-way, 2-position cartridge valve that features a direct-acting, balanced spool with closed transition between positions. This design significantly minimizes oil loss during shifting, which is especially beneficial in pilot control circuits. The valve operates effectively with port 3 as the inlet and port 1 as the tank return, though reverse flow is possible but not recommended due to potential performance variations. Engineered for robustness, the DNCADCN912N's solenoid tube assembly is fatigue rated for up to 5000 psi (350 bar), ensuring reliable operation under high-pressure conditions. Notably, this valve does not require minimum hydraulic pressure to function and can operate directly upon actuation. It incorporates EPDM seals specifically designed for use with phosphate ester fluids; however, these seals are susceptible to damage if exposed to petroleum-based substances. The valve's wet armature design allows the working fluid to surround the armature, which could be a consideration when the coil is energized continuously as some fluids may degrade under prolonged heat exposure. To accommodate various system requirements, Sun Hydraulics offers multiple coil termination and voltage options, including models with surge protection. Additionally, this model boasts a high-efficiency solenoid that provides strong spool actuating force per watt expended, enhancing the reliability of valve shifting. The coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either orientation on the tube. Options for coil connectors support up to IP69K ratings for enhanced environmental protection. The DNCADCN912N also benefits from Sun\u2019s floating style construction which reduces risks associated with internal parts binding due to excessive installation torque or variations in cavity/cartridge machining. This feature ensures more consistent performance and longevity of the valve in various hydraulic applications.
