The Sun Hydraulics DNCALBN223 (DNCALBN223) 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 ensures smooth and efficient operation with its closed transition between positions, minimizing oil loss during shifting\u2014a crucial feature for maintaining the integrity of pilot control circuits. The DNCALBN223 is engineered to handle a maximum operating pressure of 5000 psi (350 bar) and has a flow capacity of 8 gpm (30 L/min), making it suitable for a variety of demanding applications. This valve features an innovative wet armature design where the working fluid surrounds the armature, which is beneficial for heat dissipation but requires careful consideration of fluid type to avoid breakdown and varnish formation that could impair functionality. It is specifically configured with EPDM seals for compatibility with phosphate ester fluids; however, these seals are susceptible to damage if exposed to petroleum-based fluids. For added versatility and reliability in different environments, the DNCALBN223 offers various coil termination and voltage options, including models with surge protection. The coils are not only interchangeable with other Sun Series 1 solenoid products but can also be mounted in either direction on the tube. Moreover, this model incorporates Sun's floating style construction which helps prevent internal parts binding due to excessive installation torque or cavity/cartridge machining variations. With its robust magnetic design, the solenoid provides high efficiency and powerful spool actuating force per Watt expended. This ensures reliable valve shifting even under rigorous conditions. The valve also supports manual override capabilities and offers various installation features such as an IP69K rating for certain coil connector options, enhancing its suitability for harsh environments.
