The Sun Hydraulics DNCADWV648 (DNCADWV648) is a high-performance solenoid-operated, 4-way, 2-position cartridge valve. This direct-acting, balanced spool directional valve is designed for efficient control in hydraulic systems. It features a closed transition between positions to minimize oil loss during shifting, which is especially beneficial in pilot control circuits. With a capacity of 8 gpm (30 L/min) and a maximum operating pressure of 5000 psi (350 bar), the DNCADWV648 is robust and versatile for various applications. The valve's solenoid tube assembly is fatigue rated for high-pressure service, ensuring durability and longevity. It operates without requiring a minimum hydraulic pressure, allowing for flexible installation options across different system configurations. The DNCADWV648 uses EPDM seals suitable for systems with phosphate ester fluids; however, these seals must not be exposed to petroleum-based fluids as they can cause damage. Designed with a wet armature setup, the DNCADWV648's working fluid surrounds the armature which may be subject to heat during prolonged coil energization. This design consideration is crucial when using fluids like water-glycol mixtures that could degrade under heat exposure. Additionally, the valve offers an array of coil termination and voltage options, enhancing its adaptability to different electrical requirements. This model also features Sun\u2019s unique magnetic design in its solenoid construction which improves efficiency and provides strong actuating force per Watt expended. The coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. For environmental resilience, weatherized coils and kits are available to extend the valve's usability in adverse conditions. Incorporating Sun\u2019s floating style construction minimizes internal parts binding due to installation torque or machining variations of cavity/cartridge, ensuring reliable operation and ease of maintenance.
