The Sun Hydraulics DMDAXRN924 (DMDAXRN924) is a solenoid-operated, 3-way, 2-position cartridge valve designed for high-performance hydraulic systems. This direct-acting, balanced spool directional valve features a robust design with the solenoid tube assembly fatigue rated for 5000 psi (350 bar) service. The spools B and R remain closed during the transition between positions, enhancing performance by providing faster and more consistent response times, especially suitable for pilot control applications where flow capacity is less critical. This valve operates without a minimum hydraulic pressure requirement and incorporates a wet armature design, allowing the working fluid to surround the armature. Such a design is crucial in managing the heat generated by the coil during prolonged energization periods. However, it requires careful consideration of fluid type as some fluids can degrade under heat, impacting the valve's functionality. The DMDAXRN924 supports various manual override options with detents meant for temporary actuation and has an expected mechanical life of approximately 7,000 cycles. It also utilizes EPDM seals specifically for use with phosphate ester fluids; these seals are susceptible to damage if exposed to petroleum-based fluids. Additionally, its interchangeable coils compatibility with other Sun Series 1 solenoid products offers flexibility in maintenance and replacement. The valve also benefits from Sun's floating style construction which minimizes internal parts binding due to installation torque or cavity/cartridge machining variations. Key specifications include a maximum operating pressure of 5000 psi (350 bar), flow capacity up to 12 gpm (45 L/min), and swift response times typically around 50 ms. It also features minimal leakage at high pressures and can handle up to 15,000 switching cycles per hour. The manual override requires minimal force, further enhancing usability in field applications.
