The Sun Hydraulics DNCALBN612N (DNCALBN612N) is a high-performance, solenoid-operated, 4-way, 2-position cartridge valve designed for direct-acting operation with a balanced spool directional control mechanism. This valve features a closed transition between positions, which significantly minimizes oil loss during shifting\u2014this attribute is particularly beneficial in pilot control circuits where maintaining hydraulic integrity is crucial. The DNCALBN612N operates efficiently without requiring a minimum hydraulic pressure and can handle a maximum operating pressure of 5000 psi (350 bar). This model's design includes an innovative solenoid tube assembly that is fatigue rated for high-pressure applications and utilizes a wet armature setup. The wet armature design means that the working fluid surrounds the armature, which could be subjected to heat generated by the coil if energized continuously; this factor should be considered when using fluids like water-glycol mixtures that might degrade under high temperatures. The valve offers flexibility with various coil termination and voltage options, including models with surge protection and weatherized kits for enhanced environmental durability. Notably, the DNCALBN612N supports a flow capacity of up to 8 gpm (30 L/min) based on port 3 as the inlet and port 1 as the tank. However, it's advised that reverse flow configurations may not yield similar performance and are not recommended. Additional features include interchangeable coils compatible with other Sun Series 1 solenoid products, multiple connector options rated up to IP69K for robust protection against environmental elements, and Sun\u2019s proprietary floating style construction that reduces risks associated with internal parts binding. With its quick response time of approximately 50 ms and capability to handle up to 15,000 switching cycles per hour, this valve meets rigorous demands for reliable performance in varied hydraulic applications requiring precise control and minimal leakage.
