The Sun Hydraulics DMDATBN914N (DMDATBN914N) is a solenoid-operated 3-way, 2-position cartridge valve designed for high-performance hydraulic systems. This direct-acting, balanced spool directional valve is fatigue rated for demanding applications at pressures up to 5000 psi (350 bar). It features a unique closed transition between Spools B and R, enhancing performance by ensuring faster and more consistent response times, particularly suitable for pilot control applications where capacity is less critical. The DMDATBN914N operates without the need for minimum hydraulic pressure, increasing its versatility across various hydraulic systems. It incorporates manual override options with a detent mechanism designed for temporary actuation, boasting a mechanical life expectancy of around 7,000 cycles. Additionally, the valve is equipped with EPDM seals specifically configured for use with phosphate ester fluids; however, these seals are susceptible to damage if exposed to petroleum-based fluids. This model employs a wet armature design which involves the working fluid surrounding the armature, potentially affecting performance if the coil remains energized over extended periods. The valve\u2019s design also supports interchangeable coils from other Sun Series 1 solenoid products and can be installed in either direction on the tube. It incorporates Sun's floating style construction to minimize internal parts binding caused by excessive installation torque or variations in cavity/cartridge machining. Key specifications include a flow capacity of up to 12 gpm (45 L/min), maximum operating pressure of 5000 psi (350 bar), typical response time of 50 ms, and maximum leakage at 3000 psi set at 5 in\u00b3/min (80 cc/min). The switching frequency capability reaches up to 15,000 cycles per hour. Installation requires specific torque settings and manual override details are provided to ensure optimal operation and maintenance ease.
