The Sun Hydraulics DNCADSN212N (DNCADSN212N) is a high-performance, solenoid-operated, 4-way, 2-position cartridge valve that offers precise control in hydraulic systems. This direct-acting, balanced spool directional valve ensures a closed transition between positions, minimizing the loss of oil during shifting which is critical in pilot control circuits. With a capacity of 8 gpm/30 L/min and a maximum operating pressure of 5000 psi/350 bar, the DNCADSN212N is designed for robust performance. The valve features a unique solenoid tube assembly rated for fatigue at 5000 psi/350 bar service, ensuring durability and reliability under high-pressure conditions. It operates without any minimum hydraulic pressure requirement and incorporates EPDM seals specifically for use with phosphate ester fluids; however, these seals are susceptible to damage if exposed to petroleum-based fluids. Further enhancing its versatility, the DNCADSN212N uses a wet armature design where the working fluid surrounds the armature. This design consideration is crucial when the coil is energized for extended periods as it can affect fluid integrity over time. The valve also offers various coil termination and voltage options including configurations with surge protection. For environmental resilience, weatherized coils and kits are available to provide additional protection against harsh conditions. This model also benefits from Sun Hydraulics' floating style construction which helps prevent internal parts binding due to installation torque or cavity/cartridge machining variations. This valve's efficient magnetic design results in high spool actuating force per Watt expended, contributing to reliable valve shifting with a typical response time of 50 ms. It supports a switching frequency of up to 15,000 cycles/hr and allows manual override with specific force requirements depending on the pressure at port 1. The DNCADSN212N's robust build and thoughtful engineering make it an essential component for advanced hydraulic control applications requiring precise directional flow management.
