The Sun Hydraulics DMDATNN914 (DMDATNN914) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve designed for precise hydraulic control. This direct-acting, balanced spool directional valve features a robust design with a fatigue rating of 5000 psi (350 bar), making it suitable for demanding applications. The valve ensures closed transitions between its two positions (Spools B and R), enhancing performance by providing faster and more consistent response times, especially beneficial in pilot control setups where capacity is less critical. Equipped with no minimum hydraulic pressure requirement for operation, the DMDATNN914 offers flexibility in various hydraulic systems. The valve can be manually overridden temporarily using the D or L control options; however, this manual override has a mechanical life expectancy of approximately 7,000 cycles. For environments using phosphate ester fluids, cartridges with EPDM seals are recommended to prevent damage from petroleum-based substances. This model utilizes a wet armature design where the working fluid surrounds the armature. This exposure to fluid heat can affect performance if the coil remains energized over extended periods, potentially breaking down certain fluids like water-glycol mixtures into varnishes that impede cartridge function. The interchangeable coils compatible with other Sun Series 1 solenoid products offer additional versatility and can be mounted in either direction on the tube. Additional technical specifications include a maximum operating capacity of 12 gpm (45 L/min), typical response times of around 50 ms, and maximum valve leakage at 110 SUS (24 cSt) rated at 5 in\u00b3/min at 3000 psi (80 cc/min at 210 bar). The unit also supports up to 15,000 switching cycles per hour and incorporates Sun's floating style construction to reduce internal part binding due to installation stresses or cavity-cartridge machining variations.
