The Sun Hydraulics DNCADXV212 (DNCADXV212) is a high-performance solenoid-operated, 4-way, 2-position cartridge valve designed for precision control in hydraulic systems. This direct-acting, balanced spool directional valve features a closed transition between positions, minimizing oil loss during shifting\u2014a crucial feature for maintaining efficiency in pilot control circuits. With its port 3 designated as the inlet and port 1 as the tank, the valve ensures reliable operation although it allows reverse flow; however, performance in reverse configuration may not be optimal. Engineered for demanding applications, the DNCADXV212 can handle a maximum operating pressure of 5000 psi (350 bar) and has a flow capacity of up to 8 gpm (30 L/min). The solenoid tube assembly is fatigue rated for robust performance even under extreme conditions. Notably, this valve requires no minimum hydraulic pressure to operate and features 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 in certain conditions. The DNCADXV212 offers various coil termination and voltage options, including configurations with surge protection and coils rated up to IP69K for enhanced environmental resistance. Interchangeable coils with other Sun Series 1 solenoid products add versatility to this model, allowing for easy maintenance and replacement. Additionally, it incorporates Sun's floating style construction which minimizes internal parts binding that could result from excessive installation torque or cavity/cartridge machining variations. This model also boasts rapid response times typical at 50 ms and supports high switching frequencies up to 15000 cycles per hour. For environments requiring specific sealing solutions, cartridges configured with EPDM seals are available specifically for use with phosphate ester fluids. The DNCADXV212 is an exemplary choice for applications requiring precise fluid control with high reliability and adaptability.
