The Sun Hydraulics DMDAXAV836 (DMDAXAV836) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve designed for precise control in hydraulic systems. This direct-acting, balanced spool directional valve is specifically engineered to operate without minimum hydraulic pressure, enhancing its versatility in various applications. It features a fatigue-rated solenoid tube assembly capable of handling services up to 5000 psi (350 bar), making it suitable for rigorous industrial use. The DMDAXAV836 model incorporates closed transitions between Spools B and R, which although limits capacity, significantly enhances performance by providing faster and more consistent response times\u2014ideal for pilot control applications where capacity is less critical. The manual override option included in models with the D or L control uses a detent mechanism designed for temporary actuation only, with a mechanical life expectancy of around 7,000 cycles. This valve also utilizes EPDM seals suitable for phosphate ester fluids but should be avoided with petroleum-based fluids to prevent seal damage. Its wet armature design allows the working fluid to surround the armature which can be a consideration if the coil remains energized over extended periods as some fluids may degrade under heat. Additionally, the interchangeable coils with other Sun Series 1 solenoid products provide flexibility and ease of maintenance. The valve's construction includes Sun's floating style design which minimizes internal parts binding due to installation torque or cavity/cartridge machining variations. Key specifications include a maximum operating pressure of 5000 psi (350 bar), flow capacity up to 12 gpm (45 L/min), and typical response time of 50 ms. This robust configuration ensures that the DMDAXAV836 meets stringent operational demands while maintaining reliability and durability in challenging environments.
