The Sun Hydraulics DMDADBV912 (DMDADBV912) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve designed for rigorous hydraulic applications. This direct-acting, balanced spool directional valve is engineered to operate effectively without requiring a minimum hydraulic pressure, making it highly versatile and reliable in various operational environments. Its construction includes a fatigue-rated solenoid tube assembly capable of handling pressures up to 5000 psi (350 bar), ensuring durability and longevity under high-pressure conditions. The DMDADBV912 features closed transitions between Spools B and R, optimizing performance by providing faster and more consistent response times ideal for pilot control applications where capacity is less critical. The valve incorporates a wet armature design, where the working fluid surrounds the armature which can be critical when the coil is energized for extended periods; this needs consideration in systems using heat-sensitive fluids like water-glycol mixtures. For manual operation, the valve offers options with D or L control having a detent mechanism designed for temporary actuation with a mechanical life expectancy of about 7,000 cycles. Additionally, it utilizes EPDM seals suitable for systems with phosphate ester fluids while being incompatible with petroleum-based fluids that could damage these seals. With its interchangeable coils compatible with other Sun Series 1 solenoid products and floating style construction that minimizes internal parts binding, the DMDADBV912 provides flexibility in installation and maintenance. It supports up to 12 gpm (45 L/min) flow capacity and features rapid response times typically around 50 ms. This model also allows easy integration into existing hydraulic systems while offering robust performance essential for demanding applications.
