The Sun Hydraulics DMDALAN512 (DMDALAN512) is a solenoid-operated 3-way, 2-position cartridge valve that offers precise control in hydraulic systems. This direct-acting, balanced spool directional valve is engineered to operate without minimum hydraulic pressure, enhancing its versatility across various applications. The valve features a fatigue rating of 5000 psi (350 bar), suitable for high-pressure environments. The DMDALAN512 incorporates a closed transition between Spools B and R, optimizing performance by providing faster and more consistent response times, particularly suitable for pilot control applications where capacity is less critical. The manual override equipped with the D or L control includes a detent mechanism designed for temporary actuation with a mechanical life expectancy of approximately 7,000 cycles. This model uses EPDM seals specifically for systems containing phosphate ester fluids; however, these seals are susceptible to damage when exposed to petroleum-based fluids. It also utilizes a wet armature design where the working fluid surrounds the armature which could be relevant if the coil remains energized for extended periods. Interchangeable coils with other Sun Series 1 solenoid products offer flexibility in maintenance and replacement processes. The construction of the valve minimizes internal parts binding through its floating style design, accommodating variations in cavity/cartridge machining and installation torque. Key specifications include a maximum operating pressure of 5000 psi (350 bar), flow capacity up to 12 gpm (45 L/min), and typical response times around 50 ms. The valve also supports up to 15,000 switching cycles per hour making it reliable for continuous use scenarios. Overall, the Sun Hydraulics DMDALAN512 provides robust performance and reliability for specialized hydraulic applications requiring precise fluid control.
