The Sun Hydraulics DNCALCV224N (DNCALCV224N) 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, which significantly reduces oil loss during shifting\u2014a crucial benefit in pilot control circuits. The valve is notable for its robust construction with a fatigue rating of 5000 psi (350 bar), making it suitable for demanding applications. Engineered for versatility, the DNCALCV224N operates without requiring a minimum hydraulic pressure and supports reverse flow, although optimal performance in this mode isn't 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. The wet armature design of the solenoid means that the working fluid surrounds the armature which could lead to fluid degradation if the coil remains energized over extended periods. This model also stands out due to its wide range of coil termination and voltage options, including configurations with surge protection. Its coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. Additionally, the solenoid\u2019s unique magnetic design enhances efficiency by maximizing spool actuating force per watt expended. The DNCALCV224N is engineered with Sun's floating style construction which minimizes internal parts binding caused by excessive installation torque or cavity/cartridge machining variations. This feature along with an array of available weatherized coils and kits extends its usability across various environmental conditions while maintaining reliable valve operation and durability. With specifications like an 8 gpm (30 L/min) capacity and rapid response times typically around 50 ms, this valve is designed to meet rigorous industrial demands efficiently.
