The Sun Hydraulics DMDAXPN912N (DMDAXPN912N) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve designed for robust and efficient hydraulic fluid direction control. This direct-acting, balanced spool directional valve features a solenoid tube assembly rated for fatigue at 5000 psi (350 bar), making it suitable for high-pressure applications. The spools B and R maintain a closed position during the transition between two positions, optimizing performance by providing faster and more consistent response times especially in pilot control applications where capacity isn't a critical factor. This model is equipped with manual override capabilities using the D or L control options, which are intended for temporary actuation with a mechanical life expectancy of about 7,000 cycles. The valve incorporates EPDM seals suited specifically for systems utilizing phosphate ester fluids; however, these seals are susceptible to damage if exposed to petroleum-based fluids. Featuring a wet armature design, the working fluid in this valve surrounds the armature which can be significant when considering the thermal management of the system. The interchangeable coils of this model are compatible with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. Additionally, it uses Sun\u2019s floating style construction to minimize internal parts binding that could occur due to excessive installation torque or variations in cavity/cartridge machining. Key specifications include a maximum flow capacity of 12 gpm (45 L/min), typical response time of 50 ms, and maximum operating pressure of 5000 psi (350 bar). This model also supports switching frequencies up to 15,000 cycles per hour and features manual override requirements of minimal force, emphasizing its ease of use in various hydraulic setups.
