The Sun Hydraulics DNCALCN948 (DNCALCN948) is a high-performance solenoid-operated, 4-way, 2-position cartridge valve designed for precise hydraulic fluid direction control in complex systems. This direct-acting, balanced spool directional valve features a closed transition between positions, minimizing oil loss during shifting which is crucial in maintaining the efficiency of pilot control circuits. With its port 3 designated as the inlet and port 1 as the tank, the valve facilitates a maximum flow capacity of 8 gpm (30 L/min) and can withstand a maximum operating pressure of up to 5000 psi (350 bar). The DNCALCN948 valve is engineered with a fatigue-rated solenoid tube assembly capable of handling pressures up to 5000 psi for robust, long-term performance. It operates without requiring a minimum hydraulic pressure, enhancing its versatility across various applications. The wet armature design allows the working fluid to surround the armature, potentially affecting fluid integrity under prolonged energization due to heat exposure; this factor should be considered when using sensitive fluids like water-glycol mixtures. For customization to specific system requirements, the DNCALCN948 offers various coil termination and voltage options, including models with surge protection. Its coils are interchangeable with other Sun Series 1 solenoid products and can be oriented in either direction upon mounting. The environmental resilience of this model is further enhanced by optional weatherized coils and kits for comprehensive protection against harsh conditions. This model also incorporates Sun\u2019s floating style construction that reduces risks associated with internal parts binding due to installation torque or cavity/cartridge machining discrepancies. The response time for typical operation is around 50 ms, and it supports a switching frequency of up to 15,000 cycles per hour. Additional features include manual override capabilities and multiple sealing options tailored for different fluid types to ensure reliable operation and longevity in diverse industrial settings.
