The Sun Hydraulics DMDALAN224N (DMDALAN224N) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve designed for demanding hydraulic applications. It features a direct-acting, balanced spool with closed transitions between positions 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 operates without requiring a minimum hydraulic pressure, making it versatile for various system configurations. Equipped with fatigue-rated solenoid tube assemblies for up to 5000 psi (350 bar) service, the DMDALAN224N ensures durability and reliability under high-pressure conditions. Its manual override options include detent mechanisms intended for temporary actuation with a mechanical life expectancy of approximately 7,000 cycles. Notably, this model uses EPDM seals specifically designed for phosphate ester fluids; however, these seals are susceptible to damage when exposed to petroleum-based fluids. The valve's wet armature design allows the working fluid to surround the armature which may be a consideration if the coil remains energized over extended periods due to potential breakdown of certain fluid types at elevated temperatures. Furthermore, its interchangeable coils with other Sun Series 1 solenoid products offer flexibility in maintenance and replacement processes. The construction incorporates Sun's floating style design minimizing internal parts binding caused by installation torque or cavity/cartridge machining variations. Additional specifications include a flow capacity of 12 gpm (45 L/min), response times typically around 50 ms, and maximum operating pressures up to 5000 psi (350 bar). With features like these, the DMDALAN224N is adept at providing efficient directional control in sophisticated hydraulic systems requiring precise operation and robust performance.
