The Sun Hydraulics DMDALAN812N (DMDALAN812N) is a solenoid-operated 3-way, 2-position cartridge valve designed for reliable and efficient hydraulic control. Featuring a direct-acting, balanced spool design, this valve ensures high performance and durability with a maximum operating pressure of 5000 psi (350 bar). It is particularly noted for its closed transition between Spools B and R, enhancing performance by maintaining consistent response times especially in pilot control applications where capacity is less critical. The DMDALAN812N operates without requiring a minimum hydraulic pressure, making it versatile for various applications. It incorporates manual overrides with detent mechanisms designed for temporary actuation; these manual controls are robust with an estimated mechanical life of about 7,000 cycles. For environments using phosphate ester fluids, models with EPDM seals are recommended to avoid damage from petroleum-based substances. This valve model also features a wet armature design wherein the working fluid surrounds the armature. This design consideration is crucial when the coil remains energized for extended periods as it can influence fluid integrity depending on the type of hydraulic fluid used. The interchangeability of coils with other Sun Series 1 solenoid products adds to its flexibility in installation and maintenance. Additional structural benefits include the Sun floating style construction which minimizes internal parts binding\u2014a common issue arising from excessive installation torque or variations in cavity/cartridge machining. With specifications like a flow capacity of up to 12 gpm (45 L/min), typical response time of 50 ms, and very low maximum valve leakage at high pressures, the DMDALAN812N stands out as a robust solution for directional control in hydraulic systems.
