The Sun Hydraulics DNCALXN612N (DNCALXN612N) is a solenoid-operated, 4-way, 2-position cartridge valve designed for direct-acting, balanced spool directional control. This valve features a closed transition between positions, significantly minimizing oil loss during shifting, which is especially beneficial in pilot control circuits. The valve's capacity is optimized with port 3 as the inlet and port 1 as the tank; reverse flow is possible but not recommended due to potential performance degradation. It operates without requiring minimum hydraulic pressure, and its solenoid tube assembly is fatigue-rated for up to 5000 psi (350 bar). The DNCALXN612N incorporates EPDM seals suitable for systems using phosphate ester fluids; however, these seals are incompatible with petroleum-based fluids. Utilizing a wet armature design, this valve ensures the working fluid surrounds the armature. This design consideration is crucial in applications where the coil remains energized for extended periods, as some fluids may degrade under heat exposure over time. This model offers flexibility with various coil termination and voltage options available, including configurations with surge protection. The high-efficiency solenoid design delivers significant spool actuating force per watt expended, ensuring reliable operation. Coils are interchangeable within Sun's Series 1 solenoid products and can be mounted bidirectionally on the tube. Coil connector options provide protection ratings up to IP69K for enhanced environmental resilience. The DNCALXN612N incorporates Sun's floating style construction to reduce internal binding risks due to installation torque or cavity machining variations. It features a capacity of 8 gpm (30 L/min) and supports a maximum operating pressure of 5000 psi (350 bar). With a typical response time of 50 ms and capable of handling up to 15,000 cycles per hour switching frequency, this valve is both fast-acting and durable in demanding applications.
