The Sun Hydraulics DNCADJN828 (DNCADJN828) is a high-performance, solenoid-operated directional valve that offers precise control with its 4-way, 2-position cartridge configuration. Designed for robust and efficient operation, this valve features a direct-acting, balanced spool with closed transition between positions, which significantly minimizes oil loss during shifting\u2014a crucial aspect 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 DNCADJN828 ensures reliable performance even under reverse flow conditions, though optimal performance is not guaranteed in such setups. The valve operates effectively without any minimum hydraulic pressure requirement and incorporates EPDM seals specifically for use with phosphate ester fluids; however, these seals are susceptible to damage when exposed to petroleum-based fluids. This model boasts a fatigue-rated solenoid tube assembly for up to 5000 psi (350 bar) service and utilizes a wet armature design. Such design considerations mean that while the working fluid surrounds the armature providing cooling, prolonged energization could lead to fluid degradation if not monitored carefully. The DNCADJN828 also features various coil termination and voltage options, including versions with surge protection. Further enhancing its utility and durability, the valve uses Sun\u2019s floating style construction to reduce internal part binding risks due to installation torque or cavity/cartridge machining variations. This model is compatible with other Sun Series 1 solenoid products regarding coil interchangeability and can be mounted in either direction on the tube. For environments requiring rigorous specifications, additional weatherized coils and kits are available to ensure comprehensive environmental protection. The overall design ensures a high efficiency solenoid operation resulting in reliable valve shifting with minimal energy expenditure.
