The Sun Hydraulics DNCALAV72419 (DNCALAV72419) is a high-performance, solenoid-operated, 4-way, 2-position cartridge valve designed for precision in hydraulic control systems. This direct-acting, balanced spool directional valve ensures a closed transition between positions, minimizing oil loss during shifts which is crucial in maintaining the efficiency of pilot control circuits. The valve operates with a capacity based on port 3 as the inlet and port 1 as the tank, though it allows for reverse flow under specific conditions. Engineered for robust performance, the DNCALAV72419 features a solenoid tube assembly that is fatigue-rated for up to 5000 psi (350 bar), making it suitable for high-pressure applications. It functions without requiring a minimum hydraulic pressure and incorporates EPDM seals specifically designed for use with phosphate ester fluids; however, these seals are susceptible to damage if exposed to petroleum-based fluids. This model benefits from a wet armature design where the working fluid surrounds the armature. While this design aids in efficient operation, prolonged exposure to heat when the coil is energized can degrade certain types of hydraulic fluids. The DNCALAV72419 offers various coil termination and voltage options, some with surge protection, enhancing its adaptability across different system requirements. Its magnetic design achieves high efficiency and effective spool actuating force per watt expended. Additional features include interchangeable coils compatible with other Sun Series 1 solenoid products and multiple connector options rated up to IP69K for superior environmental protection. The valve also utilizes Sun's floating style construction which helps prevent internal parts binding due to installation torque or machining variations in the cavity/cartridge setup. With its swift response time and capability to handle frequent switching cycles effectively, this valve is optimized for dynamic system requirements where precise fluid control is essential.
