The Sun Hydraulics DMDADRV712 (DMDADRV712) is a solenoid-operated 3-way, 2-position cartridge valve that excels in high-pressure environments with its fatigue rating for 5000 psi (350 bar) service. This direct-acting, balanced spool directional valve features a closed transition between Spools B and R, enhancing performance by ensuring faster and more consistent response times, particularly suitable for pilot control applications where capacity is less critical. The valve's operation does not require a minimum hydraulic pressure, making it highly versatile across various hydraulic systems. Equipped with either D or L control options, the manual override in these models includes a detent mechanism designed for temporary actuation, with a mechanical life expectancy of about 7,000 cycles. For systems utilizing phosphate ester fluids, cartridges configured with EPDM seals are recommended; however, these seals must not be exposed to petroleum-based fluids as they can cause damage. The DMDADRV712 employs a wet armature design whereby the working fluid surrounds the armature. This design consideration is crucial when the coil is energized for extended periods as it can lead to fluid degradation at elevated temperatures. The interchangeable coils are compatible with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. This model also incorporates Sun's floating style construction which minimizes internal parts binding that could result from excessive installation torque or variations in cavity/cartridge machining. With features like a maximum operating pressure of 5000 psi (350 bar), capacity of 12 gpm (45 L/min), and rapid typical response time of 50 ms, the DMDADRV712 stands out as a robust solution for efficient directional control in hydraulic systems.
