The Sun Hydraulics DNCADAV628 (DNCADAV628) is a high-performance, solenoid-operated, 4-way, 2-position cartridge valve designed for precise hydraulic fluid direction control in various applications. This direct-acting, balanced spool valve features a closed transition between positions, which minimizes oil loss during shifting\u2014a critical feature for maintaining efficiency in pilot control circuits. The valve operates with a capacity of 8 gallons per minute (30 liters per minute), using port 3 as the inlet and port 1 as the tank. While reverse flow is possible through the valve, optimal performance under this condition is not assured. Constructed to handle a maximum operating pressure of 5000 psi (350 bar), the DNCADAV628 is also fatigue rated for demanding applications. It requires no minimum hydraulic pressure for operation, making it versatile across various mechanical setups. The valve's solenoid tube assembly boasts a rapid response time of approximately 50 milliseconds and can support up to 15,000 switching cycles per hour. One notable feature of this model is its wet armature design where the working fluid surrounds the armature. This design consideration is essential for applications where the coil may be energized continuously, potentially affecting fluid integrity over prolonged periods. Additionally, it incorporates Sun\u2019s floating style construction to reduce risks associated with internal parts binding due to excessive installation torque or cavity/cartridge machining variations. The DNCADAV628 offers several coil termination and voltage options including configurations with surge protection, enhancing its adaptability to different environmental conditions and technical requirements. Its coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. For environmental robustness, additional weatherized coils and kits are available to ensure reliable operation under diverse conditions.
