The Sun Hydraulics DNCADAV528 (DNCADAV528) is a high-performance, solenoid-operated directional valve designed for precise hydraulic control. This 4-way, 2-position cartridge valve features a direct-acting, balanced spool with a closed transition between positions, minimizing oil loss during shifting\u2014a crucial feature in pilot control circuits. With port 3 as the inlet and port 1 as the tank, the DNCADAV528 can handle a flow capacity of up to 8 gpm (30 L/min) and is rated for a maximum operating pressure of 5000 psi (350 bar). The valve's solenoid tube assembly is fatigue rated for high-pressure service, ensuring durability and reliability under demanding conditions. It operates without requiring a minimum hydraulic pressure, enabling versatile use across various applications. The DNCADAV528 uses EPDM seals specifically suited for phosphate ester fluids; however, exposure to petroleum-based fluids can damage these seals. Featuring a wet armature design, the DNCADAV528 allows the working fluid to surround the armature which could be subjected to heat if the coil remains energized for extended periods. This design consideration is vital when using certain fluids like water-glycol mixtures that may degrade at higher temperatures. The valve also offers various coil termination options and voltage configurations to suit different operational requirements and environments. Additionally, this model incorporates Sun's floating style construction which helps prevent internal part binding due to excessive installation torque or cavity/cartridge machining variations. With rapid response times typically around 50 ms and capable of up to 15,000 switching cycles per hour, the DNCADAV528 ensures efficient performance in hydraulic systems requiring frequent operation adjustments. Its robust construction and flexible configuration options make it an excellent choice for specialized hydraulic applications needing precise control with reliable operation.
