The Sun Hydraulics DMDAXBV612N (DMDAXBV612N) is a solenoid-operated 3-way, 2-position cartridge valve that functions as a direct-acting, balanced spool directional valve. Designed for high-performance applications, this valve is capable of operating at a maximum pressure of 5000 psi (350 bar) and has a flow capacity of 12 gpm (45 L/min). It features a quick response time of approximately 50 ms and maintains tight control with maximum leakage at 110 SUS (24 cSt) being only 5 in\u00b3/min at 3000 psi (80 cc/min at 210 bar). The DMDAXBV612N is engineered with fatigue-rated solenoid tube assemblies suitable for demanding usage conditions. It incorporates closed transitions between spools B and R to enhance performance by ensuring faster and more consistent response times, particularly useful in pilot control applications where capacity is less critical. The valve employs a wet armature design, allowing the working fluid to surround the armature which helps in heat management but requires consideration regarding fluid compatibility, especially with water-glycol mixtures that may degrade under prolonged exposure to heat. For manual operation, the valve includes an override feature with a detent mechanism designed for temporary actuation, supporting up to approximately 7,000 cycles. This model uses EPDM seals configured specifically for systems using phosphate ester fluids; however, these seals are susceptible to damage if exposed to petroleum-based fluids. Additionally, the cartridge's floating style construction minimizes internal parts binding due to installation torque or cavity/cartridge machining variations. The interchangeable coils with other Sun Series 1 solenoid products offer flexibility in mounting orientations. This robust construction and versatile design make the DMDAXBV612N an ideal choice for various hydraulic control applications requiring reliable directional control and swift actuation.
