The Sun Hydraulics DNCADXV71299 (DNCADXV71299) is a high-performance, solenoid-operated, 4-way, 2-position cartridge valve designed for precise control in hydraulic systems. This direct-acting, balanced spool directional valve features a closed transition between positions, which significantly minimizes the loss of oil during shifting\u2014a critical feature for maintaining efficiency in pilot control circuits. With a capacity of 8 gpm/30 L/min based on port 3 as the inlet and port 1 as the tank, the DNCADXV71299 ensures reliable operation even under reverse flow conditions, although optimal performance under such conditions is not guaranteed. The valve's solenoid tube assembly is robustly constructed to be fatigue rated for service at pressures up to 5000 psi (350 bar). It operates without requiring a minimum hydraulic pressure, making it versatile across various applications. This model employs EPDM seals specifically designed for use with phosphate ester fluids; however, these seals are susceptible to damage if exposed to petroleum-based fluids. The DNCADXV71299 also incorporates a wet armature design where the working fluid surrounds the armature. This configuration necessitates consideration of fluid characteristics as prolonged exposure to heat from an energized coil can degrade certain fluids. The valve offers flexibility with various coil termination and voltage options available, including models with surge protection. These coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. Additionally, connectors are designed to withstand environments up to IP69K standards. Sun Hydraulics has equipped this model with its floating style construction which minimizes internal parts binding due to excessive installation torque or variations in cavity/cartridge machining. With its swift response time of approximately 50 ms and capability for up to 15,000 switching cycles per hour, the DNCADXV71299 stands out as a reliable component for advanced hydraulic systems requiring precise flow control and directional change.
