The Sun Hydraulics DNCALCN624N (DNCALCN624N) is a high-performance, solenoid-operated, 4-way, 2-position cartridge valve designed for robust and efficient hydraulic control. This direct-acting, balanced spool directional valve features a closed transition between positions, which significantly minimizes oil loss during shifting. Such a feature is especially beneficial in pilot control circuits where maintaining hydraulic integrity is crucial. With a capacity based on port 3 as the inlet and port 1 as the tank, the DNCALCN624N ensures reliable operation even though reverse flow is possible; it is not recommended to guarantee the same performance. The valve operates without requiring a minimum hydraulic pressure, making it versatile for various applications. It incorporates an EPDM seal configuration suitable for systems using phosphate ester fluids but should avoid exposure to petroleum-based substances to prevent seal damage. This model also boasts a wet armature design where the working fluid surrounds the armature exposed to coil-generated heat\u2014a consideration for applications involving long energization periods. The DNCALCN624N offers various coil termination and voltage options, including models with surge protection. Its magnetic design enhances solenoid efficiency, ensuring high spool actuating force per watt expended for dependable valve shifting. Coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. Furthermore, connector options are available up to IP69K standards with additional weatherized coils and kits offered for enhanced environmental protection. The design also includes Sun's floating style construction which helps prevent internal parts binding due to installation torque or machining variations in cavity/cartridge setups. Overall, the Sun Hydraulics DNCALCN624N offers robust performance specifications including an operating pressure up to 5000 psi (350 bar), flow capacity of 8 gpm (30 L/min), and rapid response times typical at 50 ms. It also supports manual override capabilities and maintains minimal leakage rates under high-pressure conditions.
