The Sun Hydraulics DMDAXPN548 (DMDAXPN548) 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 solenoid tube assembly that is fatigue rated for 5000 psi (350 bar) service, ensuring durability and reliability under high-pressure conditions. The spools B and R are closed during the transition between their two positions, optimizing performance by providing faster and more consistent response times, especially in applications where capacity is not a critical factor. The DMDAXPN548 requires no minimum hydraulic pressure to operate, making it versatile for various hydraulic control systems. It includes options for manual override controls labeled D or L, which are intended for temporary actuation with a mechanical life expectancy of around 7,000 cycles. Additionally, this model can be equipped with EPDM seals suitable for phosphate ester fluids but should avoid exposure to petroleum-based fluids to prevent seal damage. This valve incorporates a wet armature design allowing the working fluid to surround the armature; however, prolonged energization of the coil should be monitored as it can lead to fluid breakdown in certain conditions. The interchangeable coils with other Sun Series 1 solenoid products offer flexibility in maintenance and replacement. Furthermore, its construction features Sun's floating style design which minimizes internal parts binding due to installation torque or machining variations of cavity/cartridge. Key specifications include a flow capacity of 12 gpm (45 L/min), maximum operating pressure of 5000 psi (350 bar), typical response time of 50 ms, and maximum valve leakage at 110 SUS (24 cSt) being 5 in\u00b3/min at 3000 psi (80 cc/min at 210 bar). The manual override requires minimal force and has a stroke length adequate for effective temporary control. This valve model weighs approximately 0.60 lb (0.30 kg), ensuring it is lightweight yet robust enough for demanding applications.
