The Sun Hydraulics DNCADAN524 (DNCADAN524) is a high-performance, solenoid-operated, 4-way, 2-position cartridge valve designed for direct-acting operation with a balanced spool directional control mechanism. This valve features a closed transition between positions, which is essential for minimizing oil loss during shifting\u2014a critical consideration in pilot control circuits. With its configuration allowing port 3 as the inlet and port 1 as the tank, the DNCADAN524 ensures efficient operation, although it is noted that reverse flow is possible but not recommended due to potential performance issues. The DNCADAN524's solenoid tube assembly is fatigue rated for up to 5000 psi (350 bar), making it robust for demanding applications. The valve does not require a minimum hydraulic pressure to operate, thereby enhancing its versatility across various hydraulic systems. It includes EPDM seals specifically for use with phosphate ester fluids; however, these seals must avoid contact with petroleum-based fluids to prevent damage. Another notable feature of this model is its wet armature design where the working fluid surrounds the armature. This design consideration is crucial if the coil remains energized for extended periods since some fluids may degrade under prolonged exposure to heat. The DNCADAN524 offers a variety of coil termination and voltage options, including models with surge protection. Its coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. This model also incorporates Sun's floating style construction which reduces risks associated with internal parts binding due to installation torque or cavity/cartridge machining variations. It supports a maximum operating pressure of 5000 psi (350 bar) and handles up to 8 gpm (30 L/min), with a typical response time of around 50 ms and maximum switching frequency of about 15000 cycles per hour. These features make the DNCADAN524 an efficient and reliable choice for controlling fluid power in various hydraulic systems.
