The Sun Hydraulics DMDALAN224 (DMDALAN224) is a solenoid-operated 3-way, 2-position cartridge valve designed for high-performance hydraulic systems. This direct-acting, balanced spool directional valve is engineered to operate efficiently with no minimum hydraulic pressure required for activation. The valve features a fatigue rating of 5000 psi (350 bar), making it suitable for rigorous applications. It incorporates a closed transition between its two positions (Spools B and R), enhancing performance by providing faster and more consistent response times, particularly useful in pilot control applications where capacity is less critical. The DMDALAN224 model includes manual override options with a mechanical life expectancy of approximately 7,000 cycles, suitable for temporary actuation. It also utilizes a wet armature design where the working fluid surrounds the armature; this design consideration is crucial when the coil remains energized over long periods as heat generated can affect certain types of hydraulic fluids. This valve offers interchangeable coils with other Sun Series 1 solenoid products and supports a maximum flow capacity of 12 gpm (45 L/min) with typical response times around 50 ms. Designed to minimize internal part binding due to installation torque or variations in cavity/cartridge machining, it employs Sun's floating style construction. The model features EPDM seals intended specifically for use with phosphate ester fluids; however, these seals are susceptible to damage by petroleum-based fluids. Additional specifications include a switching frequency of up to 15,000 cycles per hour and manual override requirements of just 5 lbs force at 1000 psi for port activation. Its robust build ensures minimal leakage and reliable operation in demanding conditions, making it an ideal choice for advanced hydraulic system applications requiring precise control and durability.
