The Sun Hydraulics DMDATPN248 (DMDATPN248) 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 fatigue rating of 5000 psi (350 bar), making it suitable for demanding applications. The model incorporates closed transitions between spools B and R, enhancing performance by providing faster and more consistent response times, particularly useful in pilot control applications where capacity is less critical. The DMDATPN248 requires no minimum hydraulic pressure to operate and includes a manual override with a detent mechanism designed for temporary actuation. With a mechanical life expectancy of approximately 7,000 cycles for models equipped with D, L, or T manual control assemblies, it ensures durability and reliability in operation. This valve model uses EPDM seals configured specifically for systems utilizing phosphate ester fluids; however, these seals are susceptible to damage if exposed to petroleum-based fluids. Additionally, the valve features a wet armature design which involves the working fluid surrounding the armature that can be affected by heat generated by the coil if energized for extended periods. The interchangeable coils compatible with other Sun Series 1 solenoid products offer flexibility in maintenance and replacement. The design also includes Sun's floating style construction which minimizes internal part binding due to installation torque or cavity-cartridge machining variations. 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 3000 psi of 5 in\u00b3/min (80 cc/min). The switching frequency can reach up to 15,000 cycles/hr. Installation requires a torque between 30-35 lbf-ft (41-47 Nm) and the model weighs approximately 0.60 lb (0.30 kg).
