The Sun Hydraulics DMDADAN848 (DMDADAN848) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for demanding hydraulic applications. This direct-acting, balanced spool directional valve ensures reliable control of hydraulic flow with its robust construction. The DMDADAN848 operates efficiently without requiring a minimum hydraulic pressure and features a fatigue rating for 5000 psi (350 bar) service, making it suitable for high-pressure environments. This model incorporates Sun Hydraulics' floating style construction which minimizes the risk of internal parts binding due to excessive installation torque or variations in cavity/cartridge machining. The spools B and R maintain a closed transition between their two positions, optimizing performance by providing faster and more consistent response times, especially useful in pilot control applications where capacity is not critical. The valve's wet armature design allows the working fluid to surround the armature, potentially affecting fluid integrity if exposed to heat for extended periods. Users should note that cartridges with EPDM seals are specifically designed for phosphate ester fluids and should avoid contact with petroleum-based substances to prevent seal damage. Interchangeability of coils with other Sun Series 1 solenoid products adds versatility to this model, as coils can be mounted in either direction on the tube. Furthermore, the manual override feature is equipped with a detent mechanism intended only for temporary actuation, supporting a mechanical life expectancy of around 7,000 cycles. With a maximum operating pressure of 5000 psi (350 bar), capacity up to 12 gpm (45 L/min), and rapid typical response time of about 50 ms, the DMDADAN848 is an effective solution for controlling flow in various hydraulic systems while ensuring durability and reliability in operation.
