The Sun Hydraulics DMDADRV612N (DMDADRV612N) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for use in hydraulic systems. This direct-acting, balanced spool directional valve operates without requiring a minimum hydraulic pressure, making it highly effective for various applications. The valve features a fatigue-rated solenoid tube assembly for up to 5000 psi (350 bar) service, ensuring durability and reliability under high-pressure conditions. The DMDADRV612N valve incorporates closed transitions between Spools B and R, optimizing performance by providing faster and more consistent response times, particularly suitable for pilot controls where capacity is less critical. It also includes a manual override with a detent mechanism designed for temporary actuation, supporting approximately 7,000 cycles of mechanical life. This model uses EPDM seals specifically suited for systems utilizing phosphate ester fluids; however, these seals are vulnerable to damage when exposed to petroleum-based fluids. Additionally, the valve's wet armature design helps manage the heat generated by the coil but requires consideration of fluid type as some may degrade under prolonged exposure to heat. Interchangeability of coils with other Sun Series 1 solenoid products adds versatility to this unit, allowing for easy maintenance and replacement. The floating style construction minimizes internal parts binding which could result from excessive installation torque or cavity/cartridge machining variations. With a maximum operating pressure of 5000 psi (350 bar), capacity up to 12 gpm (45 L/min), and quick response times typically around 50 ms, the DMDADRV612N is an efficient solution for controlling fluid direction in high-pressure hydraulic systems.
