The Sun Hydraulics DMDAMBN224N (DMDAMBN224N) 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 valve's spools, B and R, are closed during the transition between two positions which enhances performance limits while reducing capacity\u2014ideal for pilot control applications where speed and consistency are critical. The DMDAMBN224N operates without requiring a minimum hydraulic pressure, thus providing flexibility in various system conditions. Models equipped with D or L control have a manual override with a detent mechanism intended for temporary actuation, boasting a mechanical life expectancy of approximately 7,000 cycles. Specific configurations of this valve that include EPDM seals are designed for systems using phosphate ester fluids; however, these seals must avoid exposure to petroleum-based substances to prevent damage. Additionally, the valve incorporates 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 some fluids may degrade under prolonged heat exposure. The interchangeable coils compatible with other Sun Series 1 solenoid products offer versatility in maintenance and replacement processes. This product also benefits from Sun's floating style construction which minimizes internal parts binding due to installation torque or variations in cavity/cartridge machining. With features such as a maximum flow capacity of 12 gpm (45 L/min), rapid response times typically around 50 ms, and robust switching frequency capabilities up to 15,000 cycles/hr, the Sun Hydraulics DMDAMBN224N is engineered to meet rigorous industrial demands while ensuring reliability and efficiency in operation.
