The Sun Hydraulics DNCALCN814 (DNCALCN814) is a high-performance, solenoid-operated, 4-way, 2-position cartridge valve designed for direct-acting and balanced spool directional control. The valve's closed transition between positions ensures minimal oil loss during shifting, which is crucial for maintaining efficiency in pilot control circuits. This model is particularly noted for its robust construction with a solenoid tube assembly that is fatigue rated for up to 5000 psi (350 bar), making it suitable for demanding applications. The DNCALCN814 operates effectively without requiring a minimum hydraulic pressure, featuring a capacity of 8 gpm (30 L/min) based on port 3 as the inlet and port 1 as the tank. Although it allows reverse flow, optimal performance in this mode is not guaranteed. It incorporates EPDM seals specifically for use with phosphate ester fluids; however, these seals are susceptible to damage if exposed to petroleum-based substances. Sun Hydraulics has equipped this valve with a wet armature design where the working fluid surrounds the armature. This design consideration is vital when the coil remains energized for extended periods as it can lead to breakdowns in certain fluid types due to heat exposure. Additionally, the model boasts an array of coil termination and voltage options, enhancing its adaptability across different systems and environmental conditions. The DNCALCN814 also benefits from interchangeable coils compatible with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. The coils themselves are designed for high efficiency, providing significant spool actuating force per watt expended which ensures reliable valve operation even under strenuous conditions. For further customization and protection against environmental factors, various weatherized coils and kits are available. In terms of installation and maintenance, this model features Sun\u2019s floating style construction that minimizes internal parts binding caused by excessive installation torque or variances in cavity/cartridge machining. This thoughtful engineering promotes longevity and reliability of the valve in various industrial applications.
