The Sun Hydraulics DMDAMNV524 (DMDAMNV524) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve designed for precise hydraulic fluid direction control in various applications. This direct-acting, balanced spool directional valve is notable for its robust construction, featuring a fatigue rating of 5000 psi (350 bar), making it suitable for high-pressure environments. The valve operates with no minimum hydraulic pressure required, enhancing its versatility across different hydraulic systems. The DMDAMNV524 incorporates a closed transition between Spools B and R, optimizing performance by providing faster and more consistent response times ideal for pilot controls where flow capacity is less critical. It also features interchangeable coils with other Sun Series 1 solenoid products, allowing for flexible installations and maintenance. The wet armature design of the valve ensures that the working fluid surrounds the armature which can be significant in prolonged energized states as it may affect the fluid properties over time. This model uses EPDM seals specifically designed for systems employing phosphate ester fluids; however, these seals are susceptible to damage when exposed to petroleum-based fluids. For manual override operations, the DMDAMNV524 includes a detent mechanism suitable for temporary actuation with an expected mechanical life of approximately 7,000 cycles. Key specifications include a flow capacity of up to 12 gpm (45 L/min), typical response times of 50 ms, and a maximum operating pressure of 5000 psi (350 bar). Additionally, this valve model promotes ease of installation and reduced risk of internal parts binding thanks to Sun's floating style construction which accommodates cavity/cartridge machining variations effectively. The compact design weighs about 0.60 lb (0.30 kg) and can handle switching frequencies up to 15,000 cycles per hour.
