The Sun Hydraulics DNCADZN214N (DNCADZN214N) 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, minimizing oil loss during shifting which is crucial in maintaining the efficiency of pilot control circuits. The valve's design allows for port 3 to be used as the inlet and port 1 as the tank outlet, with a caution that reverse flow is possible but not recommended due to potential performance degradation. Engineered for robust operation, the DNCADZN214N boasts a fatigue-rated solenoid tube assembly capable of handling pressures up to 5000 psi (350 bar), ensuring reliable functionality under high-pressure conditions. The valve does not require a minimum hydraulic pressure for operation, making it versatile across various applications. It incorporates EPDM seals specifically for use with phosphate ester fluids; however, these seals are susceptible to damage if exposed to petroleum-based fluids. This model utilizes a wet armature design where the working fluid surrounds the armature. This setup needs consideration as prolonged coil energization can lead to fluid degradation at high temperatures. For customization and application-specific requirements, Sun Hydraulics offers an array of coil termination and voltage options including models with surge protection. Additionally, coils from this series are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. The DNCADZN214N also features Sun's floating style construction which minimizes internal parts binding due to installation torque or cavity/cartridge machining variations. With its compact design and quick response time of typically 50 ms, this valve is an effective solution for dynamic systems requiring frequent switching, supporting up to 15,000 cycles per hour.
