The Sun Hydraulics DNCADCN828 (DNCADCN828) is a high-performance, solenoid-operated, 4-way, 2-position cartridge valve designed for precise hydraulic control. This direct-acting, balanced spool directional valve features a closed transition between positions, minimizing oil loss during shifting which is crucial in pilot control circuits. The valve's design allows for port 3 to be used as the inlet and port 1 as the tank outlet; however, reverse flow is possible but not recommended due to potential performance degradation. Engineered for robustness, the DNCADCN828 can handle a maximum operating pressure of 5000 psi (350 bar) and has a flow capacity of 8 gpm (30 L/min). It includes a fatigue-rated solenoid tube assembly for long-term durability under high-pressure conditions. The solenoid features an energy-efficient magnetic design that provides strong actuating force per watt expended, ensuring reliable valve shifting even under demanding conditions. This model incorporates Sun Hydraulics' floating style construction which helps prevent internal parts from binding due to excessive installation torque or variations in cavity/cartridge machining. Additionally, it boasts rapid response times typical at around 50 ms and supports up to 15,000 switching cycles per hour. The valve also offers various coil termination and voltage options with IP69K ratings available for certain configurations. For systems using phosphate ester fluids, cartridges equipped with EPDM seals are available; however, these should not be exposed to petroleum-based fluids as they can damage the seals. The DNCADCN828 also utilizes a wet armature design where the working fluid surrounds the armature; this aspect should be considered when dealing with fluids prone to breakdown at higher temperatures caused by prolonged coil energization. Overall, the Sun Hydraulics DNCADCN828 is engineered for efficient and reliable performance in hydraulic systems requiring precise directional control of fluid flow.
