The Sun Hydraulics DMDAXRN948 (DMDAXRN948) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for precise hydraulic fluid direction control. This direct-acting, balanced spool directional valve operates without requiring a minimum hydraulic pressure, enhancing its versatility in various applications. It features a robust design with a fatigue rating of 5000 psi (350 bar) for the solenoid tube assembly, ensuring durability under high-pressure conditions. The valve is equipped with spools B and R that are closed during the transition between positions, which optimizes performance by providing faster and more consistent response times, especially suitable for pilot control applications where capacity is less critical. The manual override option available on models with D or L control includes a detent mechanism intended for temporary actuation and has a mechanical life expectancy of around 7,000 cycles. For systems using phosphate ester fluids, cartridges configured with EPDM seals are recommended to prevent damage from petroleum-based substances. The wet armature design of the valve allows the working fluid to surround the armature, which should be considered when the coil is energized for extended periods as it can lead to fluid breakdown and varnish formation affecting cartridge function. Additional features include interchangeable coils with other Sun Series 1 solenoid products and a floating style construction that minimizes internal part binding due to installation torque or cavity/cartridge machining variations. With a maximum flow capacity of 12 gpm (45 L/min) and rapid response times typically around 50 ms, this valve ensures efficient operation across various hydraulic systems.
