The Sun Hydraulics DMDAXBN624N (DMDAXBN624N) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve designed for robust industrial applications. Featuring a direct-acting, balanced spool directional control mechanism, this valve ensures reliable operation without the need for minimum hydraulic pressure. It is particularly noted for its closed transition between Spools B and R, enhancing performance by providing faster and more consistent response times ideal for pilot control applications where capacity is less critical. This model boasts a fatigue rating of 5000 psi (350 bar), making it suitable for high-pressure environments. The manual override option comes with a detent mechanism designed primarily for temporary actuation and has a mechanical life expectancy of approximately 7,000 cycles. The DMDAXBN624N utilizes EPDM seals specifically tailored for systems using phosphate ester fluids; however, these seals are vulnerable to damage if exposed to petroleum-based fluids. An additional feature of this valve is its wet armature design which allows the working fluid to surround the armature, potentially affecting performance if subjected to prolonged heat exposure typical in energized coils. This design consideration is crucial when using certain hydraulic fluids that may degrade under heat. The interchangeable coils compatible with other Sun Series 1 solenoid products offer flexibility in maintenance and replacement processes. Moreover, the floating style construction incorporated in the design minimizes internal parts binding caused by excessive installation torque or variations in cavity/cartridge machining. With specifications like a maximum operating pressure of 5000 psi (350 bar), flow capacity up to 12 gpm (45 L/min), and rapid response times typically around 50 ms, the DMDAXBN624N is engineered to meet demanding operational requirements efficiently while maintaining high reliability and durability standards essential in industrial hydraulic systems.
