The Sun Hydraulics DNCALJN928 (DNCALJN928) is a high-performance, solenoid-operated, 4-way, 2-position cartridge valve designed for efficient control in hydraulic systems. This direct-acting, balanced spool directional valve features a closed transition between positions, significantly minimizing oil loss during shifting which is particularly beneficial in pilot control circuits. The valve's capacity is optimized with port 3 as the inlet and port 1 as the tank outlet; however, while reverse flow is possible through the valve, it is not recommended as performance consistency cannot be guaranteed. Engineered for robustness, the DNCALJN928's solenoid tube assembly is fatigue rated for up to 5000 psi (350 bar), making it suitable for high-pressure applications. It operates without requiring a minimum hydraulic pressure, enhancing its versatility across various hydraulic systems. The valve\u2019s design includes EPDM seals specifically for use with phosphate ester fluids; these seals must avoid exposure to petroleum-based substances to prevent damage. A distinctive feature of this model is its wet armature design where the working fluid surrounds the armature. This design consideration is crucial when the coil remains energized for extended periods since heat generated by the coil can degrade certain fluid types like water-glycol mixtures. Additionally, Sun Hydraulics has equipped this model with a variety of coil termination and voltage options to suit different operational needs and environments. The solenoid of DNCALJN928 benefits from a unique magnetic design that enhances efficiency and ensures reliable spool actuation with high force per watt expended. Its coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. For environmental resilience, options include weatherized coils and kits rated up to IP69K for superior protection against harsh conditions. This model also incorporates Sun\u2019s floating style construction which helps prevent internal parts from binding due to excessive installation torque or variations in cavity/cartridge machining. With its quick response time and capacity to handle up to 8 gpm (30 L/min), the DNCALJN928 offers a reliable solution for directing flow efficiently within advanced hydraulic systems.
