The Sun Hydraulics DNCADCN214N (DNCADCN214N) is a high-performance, solenoid-operated, 4-way, 2-position cartridge valve. This direct-acting, balanced spool directional valve ensures a closed transition between positions, minimizing oil loss during shifting\u2014a critical feature for pilot control circuits. The valve is designed to operate with port 3 as the inlet and port 1 as the tank, though it does allow for reverse flow under certain conditions. With a maximum operating pressure of 5000 psi (350 bar) and a capacity of 8 gpm (30 L/min), the DNCADCN214N is robust enough for demanding applications. The solenoid tube assembly of this valve is fatigue rated for high-pressure service, ensuring durability and longevity. It features an innovative magnetic design that enhances solenoid efficiency, resulting in higher spool actuating force per watt expended which contributes to reliable valve shifting. This model incorporates Sun\u2019s floating style construction which helps prevent internal parts from binding due to excessive installation torque or cavity/cartridge machining variations. Additionally, the valve utilizes 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 influences fluid integrity by potentially leading to breakdown and varnish formation. The DNCADCN214N offers various coil termination and voltage options, including models with surge protection. These coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. Environmental protection options extend to weatherized coils and kits that further enhance durability against harsh conditions. In terms of maintenance and adjustments, this model supports easy access to manual overrides requiring minimal force even at high pressures. Its quick response time (50 ms typical) and high switching frequency (up to 15,000 cycles/hr) make it an efficient choice for systems requiring frequent operation adjustments or rapid response times.
