The Sun Hydraulics DNCADCN211 (DNCADCN211) is a high-performance, solenoid-operated, 4-way, 2-position cartridge valve. This direct-acting, balanced spool directional valve is designed with a closed transition between positions, ensuring minimal oil loss during shifting\u2014a critical feature for pilot control circuits. The valve operates efficiently with port 3 as the inlet and port 1 as the tank, although it allows for reverse flow. Notably, its solenoid tube assembly is fatigue rated for robust service at pressures up to 5000 psi (350 bar). The DNCADCN211 requires no minimum hydraulic pressure for operation due to its direct actuation. It features EPDM seals suited specifically for systems using phosphate ester fluids; however, these seals are vulnerable to damage when exposed to petroleum-based fluids. A wet armature design characterizes this model where the working fluid surrounds the armature; this could be a concern if the coil remains energized over extended periods as some fluids might degrade under heat. This model offers an array of coil termination and voltage options, including configurations with surge protection. Its coils are interchangeable across other Sun Series 1 solenoid products and can be mounted in either direction on the tube. The solenoid\u2019s design enhances magnetic efficiency, which translates into high spool actuating force per watt expended, ensuring reliable valve shifting. Additional features include an IP69K rating option for coil connectors and availability of weatherized coils and kits for enhanced environmental protection. The DNCADCN211 also incorporates Sun's floating style construction to minimize internal parts binding due to installation torque or machining variations in cavity-cartridge setups. Overall, the Sun Hydraulics DNCADCN211 offers versatile configuration options and robust performance specifications suitable for demanding hydraulic applications requiring precise control and reliability.
