The Sun Hydraulics DMDATBN612 (DMDATBN612) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for precise hydraulic fluid direction control in various applications. This direct-acting, balanced spool directional valve operates without requiring a minimum hydraulic pressure, making it highly effective in systems where consistent performance is critical. The valve features a fatigue rating for up to 5000 psi (350 bar), ensuring durability and reliability under high-pressure conditions. Notably, the DMDATBN612 incorporates closed transitions between Spools B and R, optimizing performance by providing faster and more consistent response times at the cost of reduced flow capacity. This characteristic makes it particularly suitable for pilot control applications where flow capacity is less critical than response time. Additionally, the valve supports manual override options with a mechanical life expectancy of approximately 7,000 cycles, enhancing its usability in temporary actuation scenarios. Equipped with EPDM seals, the DMDATBN612 is tailored for use with phosphate ester fluids; however, these seals are susceptible to damage if exposed to petroleum-based fluids. It utilizes a wet armature design which could affect fluid integrity if exposed to prolonged heat from coil energization. The design also includes interchangeable coils compatible with other Sun Series 1 solenoid products and features Sun's floating style construction which minimizes internal binding due to installation variances. This model can handle up to 12 gpm (45 L/min) capacity and offers quick response times typically around 50 ms. It also boasts robust switching capabilities up to 15,000 cycles per hour while maintaining maximum leakage control at high pressures. The compact design includes a manual override feature requiring minimal force and provides easy installation with specific torque settings. Overall, the Sun Hydraulics DMDATBN612 valve offers a reliable solution for efficient directional control in hydraulic systems.
