The Sun Hydraulics DMDATRN223 (DMDATRN223) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve designed for robust hydraulic system applications. This direct-acting, balanced spool directional valve features a fatigue rating of 5000 psi (350 bar), making it suitable for demanding environments. The valve ensures closed transitions between its two positions with 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. With no minimum hydraulic pressure required for operation, the DMDATRN223 offers flexibility in various installation scenarios. The manual override feature includes a detent mechanism designed for temporary actuation and has a mechanical life expectancy of around 7,000 cycles. It's important to note that cartridges with EPDM seals are intended specifically for systems utilizing phosphate ester fluids; exposure to petroleum-based substances can damage these seals. The valve incorporates a wet armature design where the working fluid surrounds the armature, which could be significant if the coil remains energized over extended periods as heat buildup might affect certain fluid types. Interchangeability of coils with other Sun Series 1 solenoid products adds versatility to this model, allowing for easier maintenance and replacement processes. Additional features include Sun\u2019s floating style construction which minimizes internal parts binding due to installation torque or cavity-cartridge machining variations. With specifications such as a maximum operating pressure of 5000 psi (350 bar), flow capacity up to 12 gpm (45 L/min), and typical response times of 50 ms, this valve is engineered to meet rigorous industrial requirements while ensuring reliability and efficiency in hydraulic systems operations.
