The Sun Hydraulics DNCALSV224N (DNCALSV224N) is a solenoid-operated, 4-way, 2-position cartridge valve designed for precise directional control in hydraulic systems. This direct-acting, balanced spool directional valve is engineered with a closed transition between positions to minimize oil loss during shifting, making it particularly beneficial for pilot control circuits. The valve's capacity is optimized with port 3 as the inlet and port 1 as the tank; reverse flow is possible but not recommended due to potential performance degradation. It operates efficiently under high pressures up to 5000 psi (350 bar) without requiring minimum hydraulic pressure, thanks to its direct actuation. The DNCALSV224N features a wet armature design, where the working fluid surrounds the armature and absorbs heat generated by the coil. This design consideration is crucial for applications where coils are energized for extended periods, as certain fluids may degrade under heat exposure over time. A key advantage of this valve is its high-efficiency solenoid with a unique magnetic design that provides significant spool actuating force per watt expended, ensuring reliable operation. This model supports various coil termination and voltage options, including those with surge protection, and its coils are interchangeable with other Sun Series 1 solenoid products. For enhanced environmental protection, additional weatherized coils and kits are available. The valve incorporates Sun's floating style construction to reduce internal part binding risks due to installation torque or machining variations. With a maximum capacity of 8 gpm (30 L/min) and capable of handling up to 15,000 cycles per hour switching frequency, this valve offers robust performance in demanding applications. It also includes manual override capabilities for added operational flexibility. The DNCALSV224N comes equipped with Viton seals suitable for systems using phosphate ester fluids but should not be used with petroleum-based substances.
