The Sun Hydraulics DMDAMRN624 (DMDAMRN624) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for use in hydraulic systems. This direct-acting, balanced spool directional valve features a fatigue rating of 5000 psi (350 bar), making it suitable for demanding applications. The transition between the two positions of the spools B and R is closed, which enhances performance but reduces capacity. This characteristic is particularly beneficial in pilot control applications where capacity is less critical than response time. The DMDAMRN624 operates without requiring a minimum hydraulic pressure, thus ensuring reliable functionality under various conditions. It includes manual override options with a detent mechanism designed for temporary actuation and boasts a mechanical life expectancy of about 7,000 cycles. The valve's compatibility with EPDM seals makes it suitable for systems using phosphate ester fluids; however, exposure to petroleum-based fluids should be avoided as it could damage the seals. Additionally, this model utilizes a wet armature design where the working fluid surrounds the armature, potentially affecting fluid integrity if subjected to prolonged heat exposure from an energized coil. The interchangeable coils with other Sun Series 1 solenoid products offer flexibility in maintenance and replacement processes. The design also incorporates Sun's floating style construction to minimize internal parts binding due to installation torque or cavity/cartridge machining variations. Key specifications include a flow capacity of 12 gpm (45 L/min), typical response times of approximately 50 ms, maximum operating pressure capability of 5000 psi (350 bar), and switching frequency up to 15,000 cycles per hour. These features make the DMDAMRN624 an adaptable solution for various hydraulic control applications demanding robust performance and reliability.
