The Sun Hydraulics DNCALBN824 (DNCALBN824) is a high-performance, solenoid-operated, 4-way, 2-position cartridge valve designed for precise control in hydraulic systems. This direct-acting, balanced spool directional valve features a closed transition between positions, which significantly minimizes oil loss during shifting. This characteristic is especially beneficial in pilot control circuits where maintaining hydraulic integrity is crucial. With a capacity of 8 gpm/30 L/min and a maximum operating pressure of 5000 psi/350 bar, the DNCALBN824 ensures robust performance in various applications. The valve is unique in that it does not require a minimum hydraulic pressure to operate, making it versatile for different hydraulic setups. It is equipped with EPDM seals specifically for use with phosphate ester fluids; however, these seals are susceptible to damage if exposed to petroleum-based fluids. The DNCALBN824 incorporates a wet armature design where the working fluid surrounds the armature. This design consideration is vital as prolonged energization of the coil can lead to fluid degradation at high temperatures. To accommodate different system requirements, this model offers a variety of coil termination and voltage options, including configurations with surge protection. For enhanced durability and reliability, the valve features Sun\u2019s floating style construction which helps prevent internal parts binding due to excessive installation torque or variations in cavity/cartridge machining. Additionally, its solenoid\u2019s magnetic design optimizes efficiency by generating high spool actuating force per Watt expended, ensuring reliable valve operation even under demanding conditions. This model also supports interchangeable coils with other Sun Series 1 solenoid products and allows for coil mounting in either direction. The availability of additional weatherized coils and kits further extends its suitability for harsh environmental conditions. With these advanced features and configurations, the Sun Hydraulics DNCALBN824 offers superior performance and flexibility for managing directional control in hydraulic systems.
