The Sun Hydraulics DNCADBV828 (DNCADBV828) is a high-performance, solenoid-operated, 4-way, 2-position cartridge valve designed for precise hydraulic control in various applications. This direct-acting, balanced spool directional valve features a closed transition between positions, minimizing oil loss during shifting which is particularly beneficial in pilot control circuits. The DNCADBV828 operates effectively with a flow capacity of 8 gpm (30 L/min) and can handle a maximum operating pressure of 5000 psi (350 bar). Notably, the valve is engineered for durability with a fatigue rating for the solenoid tube assembly at 5000 psi. This model is versatile with its ability to accommodate reverse flow, although optimal performance in this mode isn't guaranteed. The wet armature design of the valve ensures that the working fluid surrounds the armature; however, users should be cautious as prolonged energization can lead to fluid degradation at high temperatures. The DNCADBV828 offers a variety of coil termination and voltage options, enhancing adaptability and performance across different settings. The construction incorporates Sun's floating style which minimizes internal part binding due to installation torque or machining variations of cavity/cartridge. With rapid response times typically around 50 ms and capable of up to 15,000 switching cycles per hour, this valve ensures reliable and efficient operation. Its manual override features require minimal force, making it user-friendly even under pressure conditions. Designed for robustness and reliability in demanding environments, the DNCADBV828 also supports interchangeable coils with other Sun Series 1 solenoid products and offers multiple sealing options compatible with various fluids including phosphate ester fluids through EPDM seals configuration. This product stands out for its high efficiency solenoid design that delivers superior spool actuating force per watt expended, ensuring consistent performance and reliability in hydraulic systems control.
