The Sun Hydraulics DMDATRN624 (DMDATRN624) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for robust hydraulic system applications. This direct-acting, balanced spool directional valve stands out with its fatigue rating of 5000 psi (350 bar), making it suitable for high-pressure operations. The DMDATRN624 features spools B and R which are closed in the transition between positions, enhancing performance limits while sacrificing some capacity\u2014ideal for pilot controls where speed and consistency are crucial over capacity. The valve operates without requiring a minimum hydraulic pressure, facilitating its use in a variety of systems including those with low-pressure environments. It includes manual override options with detent mechanisms designed for temporary actuation only, boasting a mechanical life expectancy of about 7,000 cycles. Notably, this model can be equipped with EPDM seals specifically for use with phosphate ester fluids; however, these seals must avoid exposure to petroleum-based substances to prevent damage. The wet armature design of the DMDATRN624 allows the working fluid to surround the armature which is beneficial but requires consideration regarding heat generation if the coil remains energized over extended periods. This could lead to breakdowns in certain fluid types like water-glycol mixtures at high temperatures. For flexibility in system design, its coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction. Incorporating Sun's floating style construction minimizes internal part binding due to variations in installation torque or cavity/cartridge machining, ensuring reliable operation and longevity of the component within hydraulic systems. The valve supports up to 12 gpm (45 L/min) capacity and offers swift response times typically around 50 ms, suitable for systems requiring quick actuations.
