The Sun Hydraulics DMDAXNN (DMDAXNN) is a solenoid-operated 3-way, 2-position cartridge valve that offers robust performance in a compact design. This direct-acting, balanced spool directional valve is specifically engineered to handle maximum operating pressures up to 5000 psi or 350 bar, making it suitable for high-pressure applications. Its solenoid tube assembly is fatigue rated for demanding conditions, ensuring durability and long service life. This model features closed transitions between Spools B and R, enhancing performance by providing faster and more consistent response times during the shift from one position to another. Such a configuration is particularly beneficial in applications where rapid actuation and precise control are required. The valve's direct actuation design requires no minimum hydraulic pressure to operate, which facilitates its use in various fluid power systems without additional pressure support. Equipped with EPDM seals, the DMDAXNN cartridge is compatible with phosphate ester fluids, although it should not be exposed to petroleum-based fluids as these can damage the seals. It also incorporates a wet armature design where the working fluid surrounds the armature; this feature needs consideration regarding fluid type and operational duration due to potential heat buildup. The interchangeable coils of this valve are compatible with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. Moreover, its floating style construction minimizes internal parts binding caused by excessive installation torque or variations in cavity/cartridge machining. With a manual override feature that includes a detent mechanism designed for temporary actuation, and a mechanical life expectancy of approximately 7,000 cycles for models with D, L or T controls, the DMDAXNN offers flexibility and reliability in manual operations as well. This valve supports up to 12 gpm/45 L/min capacity and features quick response times typically around 50 ms.
