The Sun Hydraulics DMDALNV248 (DMDALNV248) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve designed for precise hydraulic control in various applications. This direct-acting, balanced spool directional valve operates without the need for minimum hydraulic pressure, enabling reliable functionality across a range of conditions. It features a robust solenoid tube assembly rated for fatigue at 5000 psi (350 bar), ensuring durability and resilience under high-pressure operations. The DMDALNV248 valve offers closed transitions between its two positions (Spools B and R), enhancing performance by providing faster and more consistent response times, especially suitable as pilot controls where capacity is less critical. The manual override option included in models with D or L control is primarily intended for temporary actuation, with a mechanical life expectancy of around 7,000 cycles. Additionally, this model incorporates EPDM seals configured specifically for use with phosphate ester fluids; however, these seals are susceptible to damage if exposed to petroleum-based substances. A notable feature of the DMDALNV248 is its wet armature design which immerses the armature in the working fluid to manage heat dissipation from the coil. This design consideration is crucial when the coil remains energized over extended periods as it can influence fluid integrity in certain conditions. The interchangeable coils compatible with other Sun Series 1 solenoid products add versatility to this unit, allowing for easy maintenance and replacement. Furthermore, Sun Hydraulics has equipped this valve with their floating style construction to minimize internal part 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 DMDALNV248 is engineered to meet rigorous industrial demands while maintaining high efficiency and reliability in system operations.
