The Sun Hydraulics DNCALCV (DNCALCV) is a high-performance, solenoid-operated, 4-way, 2-position cartridge valve designed for direct-acting operation. This balanced spool directional valve features a closed transition between positions, which is essential for minimizing oil loss during shifting\u2014a critical feature in pilot control circuits. The DNCALCV operates efficiently with a valve capacity that considers port 3 as the inlet and port 1 as the tank, although it allows for reverse flow under certain conditions. Rated for up to 5000 psi (350 bar), the solenoid tube assembly of this valve is fatigue rated, ensuring durability and reliability in demanding applications. The DNCALCV does not require a minimum hydraulic pressure to function due to its direct-acting nature. It incorporates EPDM seals specifically designed for use with phosphate ester fluids; however, these seals are susceptible to damage when exposed to petroleum-based fluids. One of the distinctive features of this model is its wet armature design where the working fluid surrounds the armature. This design consideration is vital when the coil is energized for extended periods as some fluids may degrade at high temperatures. The valve offers various coil termination and voltage options, enhancing its adaptability to different operational environments with or without surge protection. Furthermore, Sun Hydraulics has engineered this model with interchangeable coils that are compatible with other Sun Series 1 solenoid products, offering flexibility in maintenance and replacement tasks. The coils can be mounted on either direction on the tube and come with connector options that meet up to IP69K standards. Lastly, the DNCALCV benefits from Sun\u2019s floating style construction which minimizes internal parts binding\u2014a common issue caused by excessive installation torque or variations in cavity/cartridge machining. This design feature ensures consistent performance and longevity of the valve in various hydraulic systems.
