The Sun Hydraulics DMDATBN628 (DMDATBN628) is a high-performance solenoid-operated 3-way, 2-position cartridge valve that features a direct-acting, balanced spool design. This valve is specifically engineered to handle a maximum operating pressure of 5000 psi (350 bar) and has a flow capacity of 12 gpm (45 L/min). The unit's response time is exceptionally rapid at approximately 50 ms, ensuring quick and efficient operations. Key to its functionality, the DMDATBN628 incorporates closed transitions between Spools B and R, optimizing performance by providing faster and more consistent response times ideal for pilot control applications where capacity is less critical. The valve operates without requiring a minimum hydraulic pressure, enhancing its versatility across various applications. This model also includes a manual override feature with a detent mechanism designed for temporary actuation. It supports approximately 7,000 cycles of mechanical life expectancy in models equipped with D or L control. For environments using phosphate ester fluids, cartridges configured with EPDM seals are recommended as they are resistant to these chemicals; however, exposure to petroleum-based fluids should be avoided as it can damage the seals. The DMDATBN628 utilizes interchangeable coils compatible with other Sun Series 1 solenoid products and features a wet armature design where the working fluid surrounds the armature. This design consideration is crucial when the coil remains energized for extended periods as it impacts fluid integrity over time. Moreover, this valve benefits from Sun's floating style construction which minimizes internal parts binding\u2014a common issue arising from excessive installation torque or variations in cavity/cartridge machining. This thoughtful engineering ensures reliable and consistent performance under varying operational conditions.
