The Sun Hydraulics DMDAXNN914N (DMDAXNN914N) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve designed for hydraulic systems requiring reliable directional control. This direct-acting, balanced spool valve features a robust design with a fatigue rating of 5000 psi (350 bar), making it suitable for high-pressure applications. The valve's spools, identified as B and R, are closed during the transition between positions to enhance performance by providing faster and more consistent response times, especially beneficial in pilot control applications where capacity is less critical. The DMDAXNN914N operates without the need for minimum hydraulic pressure and incorporates a wet armature design where the working fluid surrounds the armature. This design consideration is crucial as prolonged energization of the coil can heat the fluid, potentially leading to breakdown in certain fluid types like water-glycol mixtures. The valve is equipped with EPDM seals intended specifically for systems using phosphate ester fluids; however, these seals are susceptible to damage if exposed to petroleum-based fluids. Interchangeability of coils with other Sun Series 1 solenoid products adds versatility to this model, allowing for easier maintenance and replacement processes. Additionally, its floating style construction minimizes internal parts binding caused by excessive installation torque or variations in cavity/cartridge machining. Key specifications include a maximum flow capacity of 12 gpm (45 L/min), quick response time typically around 50 ms, and maximum leakage at 3000 psi not exceeding 5 in\u00b3/min. The manual override feature requires an actuation force of about 5 lbs at 1000 psi on Port 1 and allows for a stroke of .10 inches. These technical attributes ensure that the DMDAXNN914N provides efficient and reliable performance in various hydraulic applications.
