The Sun Hydraulics DMDADRN224N (DMDADRN224N) 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 features a fatigue-rated solenoid tube assembly capable of handling services up to 5000 psi (350 bar), making it suitable for high-pressure environments. Its design includes closed transitions between Spools B and R, enhancing performance by providing faster and more consistent response times, particularly beneficial in pilot control applications where capacity is less critical. The DMDADRN224N operates without the need for minimum hydraulic pressure and incorporates a manual override with a detent mechanism intended for temporary actuation. The mechanical life expectancy of its manual control assembly (D, L, and T types) is approximately 7,000 cycles. This model uses EPDM seals specifically for systems utilizing phosphate ester fluids; however, these seals are susceptible to damage if exposed to petroleum-based fluids. Additionally, the valve employs a wet armature design where the working fluid surrounds the armature which can be heated during prolonged coil energization\u2014a consideration when using certain fluid types like water-glycol mixtures that may degrade under high temperatures. The interchangeable coils with other Sun Series 1 solenoid products offer flexible mounting options and are designed to minimize internal parts binding due to installation or machining variations thanks to Sun\u2019s floating style construction. Key specifications include a flow capacity of 12 gpm (45 L/min), maximum operating pressure of 5000 psi (350 bar), typical response time of 50 ms, and maximum valve leakage at 110 SUS (24 cSt) being 5 in\u00b3/min at 3000 psi (80 cc/min at 210 bar). Its compact dimensions and robust construction make it an essential component in advanced hydraulic systems requiring precise control and reliability under high-pressure conditions.
