The Sun Hydraulics DMDALNN2E12V (DMDALNN2E12V) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve designed for robust hydraulic system applications. This direct-acting, balanced spool directional valve is notable for its fatigue rating of 5000 psi (350 bar), making it suitable for demanding operational conditions. The valve features closed transitions between 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 DMDALNN2E12V operates without the need for a minimum hydraulic pressure, offering flexibility in various system configurations. It includes a manual override with a detent mechanism designed for temporary actuation, supporting mechanical life expectancy of approximately 7,000 cycles. The model incorporates EPDM seals suited for systems utilizing phosphate ester fluids while cautioning against exposure to petroleum-based substances which could degrade the seals. This valve utilizes a wet armature design where the working fluid surrounds the armature; this design consideration is crucial when the coil is energized for extended periods as it can affect fluid integrity over time. The interchangeable coils with other Sun Series 1 solenoid products add to its versatility and ease of maintenance. Furthermore, Sun\u2019s floating style construction minimizes internal parts binding which might occur due to excessive installation torque or cavity/cartridge machining variations. Key specifications include a flow capacity of 12 gpm (45 L/min), typical response time of 50 ms, and maximum operating pressure of 5000 psi (350 bar). The valve also supports a switching frequency of up to 15,000 cycles per hour. These features make the DMDALNN2E12V an excellent choice for applications requiring reliable and precise control in hydraulic systems.
