The Sun Hydraulics DNCADLN71299 (DNCADLN71299) is a high-performance solenoid-operated, 4-way, 2-position cartridge valve. This direct-acting, balanced spool directional valve features a closed transition between positions to minimize oil loss during shifting, which is crucial in maintaining the efficiency of pilot control circuits. The valve's design allows for port 3 to be used as the inlet and port 1 as the tank, although reverse flow is possible but not recommended due to potential performance limitations. With a robust solenoid tube assembly rated for fatigue at 5000 psi (350 bar), the DNCADLN71299 ensures reliable operation under demanding conditions. It operates without requiring a minimum hydraulic pressure, enhancing its versatility across various applications. The wet armature design of the valve means that the working fluid surrounds the armature, potentially affecting fluid integrity if exposed to prolonged heat from an energized coil. This model offers an array of coil termination and voltage options, including configurations with surge protection. Its magnetic design enhances solenoid efficiency, providing strong spool actuating force per watt expended which ensures consistent and reliable valve shifting. Notably, coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. Additionally, this valve supports environmental adaptability with IP69K-rated coil connector options and additional weatherized coils for enhanced protection against harsh conditions. It also incorporates Sun\u2019s floating style construction which helps prevent internal parts binding caused by excessive installation torque or variations in cavity/cartridge machining. Key specifications include a maximum operating pressure of 5000 psi (350 bar), flow capacity up to 8 gpm (30 L/min), and typical response time of about 50 ms. The DNCADLN71299 is designed for optimal performance and reliability in specialized hydraulic systems requiring precise control and minimal fluid loss during operation transitions.
