The Sun Hydraulics DMDADNV612N (DMDADNV612N) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve. This direct-acting, balanced spool directional valve is designed for robust operation with a maximum operating pressure of 5000 psi (350 bar) and a flow capacity of 12 gpm (45 L/min). The valve features spools B and R that are closed in transition, enhancing performance by ensuring faster and more consistent response times, particularly suitable for applications as pilot controls where capacity is less critical. This model is directly actuated and operates without the need for minimum hydraulic pressure. It incorporates a wet armature design where the working fluid surrounds the armature which can be critical when the coil is energized for extended periods. The heat from the coil may affect certain fluids like water-glycol mixtures by breaking them down into varnishes that could impair cartridge function. The DMDADNV612N offers interchangeable coils with other Sun Series 1 solenoid products, allowing for flexible installation orientations. It also features Sun's floating style construction which minimizes internal parts binding caused by excessive installation torque or cavity-cartridge machining variations. For manual override operations, models equipped with D or L control have a detent mechanism designed for temporary actuation with a mechanical life expectancy of about 7,000 cycles. Additionally, cartridges configured with EPDM seals are specifically intended for systems using phosphate ester fluids; these seals are susceptible to damage if exposed to petroleum-based fluids. Overall, the Sun Hydraulics DMDADNV612N valve provides reliable performance in various hydraulic systems requiring precise control over fluid direction and flow.
