The Sun Hydraulics DNCADWV212N (DNCADWV212N) 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 especially beneficial in pilot control circuits. The valve's configuration allows for port 3 to be used as the inlet and port 1 as the tank, though reverse flow is possible but not recommended due to potential performance issues. With a capacity of up to 8 gpm (30 L/min) and a maximum operating pressure of 5000 psi (350 bar), the DNCADWV212N is equipped to handle demanding applications. It boasts a quick response time of approximately 50 ms and maintains tight control over leakage with maximum valve leakage at 110 SUS (24 cSt) being limited to 10 in\u00b3/min at 3000 psi (160 cc/min at 210 bar). The solenoid tube assembly within this model is fatigue rated for high-pressure service up to 5000 psi. The DNCADWV212N uses EPDM seals when configured for systems utilizing phosphate ester fluids; however, these seals must avoid exposure to petroleum-based fluids which can cause damage. This model also employs a wet armature design where the working fluid surrounds the armature, potentially affecting fluid properties if exposed to prolonged heat from an energized coil. Sun Hydraulics has incorporated several design features into this model such as interchangeable coils compatible with other Sun Series 1 solenoid products, various coil termination and voltage options including surge protection, and environmental protection enhancements like weatherized coils. The unique magnetic design of the solenoid ensures high efficiency and reliable valve shifting. Furthermore, its floating style construction minimizes internal parts binding that could result from excessive installation torque or cavity/cartridge machining variations.
