The Sun Hydraulics DMDALRV524 (DMDALRV524) is a solenoid-operated 3-way, 2-position cartridge valve designed for high-performance hydraulic systems. This direct-acting, balanced spool directional valve is notable for its robust construction and high fatigue rating, suitable for up to 5000 psi (350 bar) service. The valve features closed transitions between Spools B and R, enhancing performance by providing faster and more consistent response times, particularly when used as pilot controls where capacity is less critical. The DMDALRV524 operates without requiring a minimum hydraulic pressure, making it versatile across various applications. It includes manual override options with a detent mechanism designed for temporary actuation, supporting mechanical life expectancy around 7,000 cycles. The valve's compatibility with EPDM seals makes it suitable for systems using phosphate ester fluids; however, these seals must not be exposed to petroleum-based fluids as they can cause damage. A distinctive aspect of the DMDALRV524 is its wet armature design which involves the working fluid surrounding the armature. This design consideration is crucial when the coil remains energized for extended periods as heat transfer can affect fluid integrity. Additionally, the valve's coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction, providing flexibility in installation. This model also incorporates Sun\u2019s floating style construction which minimizes internal parts binding resulting from excessive installation torque or cavity/cartridge machining variations. With a capacity of 12 gpm (45 L/min) and fast response times typically around 50 ms, along with maximum operating pressure capabilities of 5000 psi (350 bar), this valve is engineered to meet demanding hydraulic control requirements efficiently.
