The Sun Hydraulics DNCALBN524 (DNCALBN524) is a high-performance, solenoid-operated, 4-way, 2-position cartridge valve, specifically designed for direct-acting and balanced spool directional control. Featuring a closed transition between positions, this valve effectively minimizes oil loss during shifting\u2014a critical feature in maintaining the efficiency and reliability of pilot control circuits. The DNCALBN524 operates optimally with port 3 as the inlet and port 1 as the tank outlet, although reverse flow is possible with altered performance expectations. Engineered for durability, the solenoid tube assembly of this valve is fatigue rated for up to 5000 psi (350 bar), ensuring robust performance under demanding conditions. Additionally, it requires no minimum hydraulic pressure for operation, enhancing its versatility across various hydraulic systems. The valve incorporates EPDM seals configured for compatibility with phosphate ester fluids; however, exposure to petroleum-based fluids should be avoided as it can damage the seals. This model also benefits from a wet armature design where the working fluid surrounds the armature which may be subject to heat during prolonged coil energization. Careful consideration of fluid selection is advised to prevent breakdown and potential varnishing that could impair cartridge function. A broad array of coil termination and voltage options are available to suit diverse operational requirements and environments. The coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. Moreover, the DNCALBN524 features Sun's innovative floating style construction which reduces risks associated with internal parts binding due to installation torque or cavity/cartridge machining variations. With a manual override option available, this valve provides both flexibility and control in application, ensuring reliable operation even under varying environmental conditions or system demands.
