The Sun Hydraulics DNCALWN828 (DNCALWN828) is a solenoid-operated, 4-way, 2-position cartridge valve that features a direct-acting, balanced spool directional design. This valve is engineered for applications where minimizing oil loss during shifting is crucial, such as in pilot control circuits. It operates with a closed transition between positions to reduce oil leakage. The valve's capacity is optimized with port 3 as the inlet and port 1 as the tank; reverse flow is possible but not recommended due to potential performance issues. Designed for high-pressure environments, the solenoid tube assembly is rated for fatigue at 5000 psi (350 bar). The valve operates directly without needing minimum hydraulic pressure and incorporates EPDM seals suitable for systems using phosphate ester fluids\u2014though these seals are incompatible with petroleum-based substances. A unique wet armature design surrounds the armature with working fluid which can affect performance if the coil remains energized long-term, especially in systems using water-glycol mixtures that may degrade under heat exposure. The solenoid's magnetic design ensures efficient operation with high actuating force per Watt, enhancing reliability in valve shifting. Coils are interchangeable within Sun Series 1 products and can be mounted bi-directionally on the tube. Various coil termination and voltage options are available, including configurations offering up to IP69K protection for harsh environments. The valve integrates Sun's floating style construction to prevent internal part binding due to installation torque or machining variations. It fits into cavity T31A and belongs to Series 1, supporting a flow capacity of up to 8 gpm (30 L/min) at a maximum operating pressure of 5000 psi (350 bar). With typical response times of approximately 50 ms and capable of handling up to 15,000 cycles per hour, this robust component also offers manual override capabilities requiring minimal force.
