The Sun Hydraulics DNCALBN914N (DNCALBN914N) 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 is notable for its closed transition between positions, which significantly minimizes oil loss during shifting\u2014a crucial feature for maintaining efficiency in pilot control circuits. The valve operates with a capacity based on port 3 as the inlet and port 1 as the tank, though it does allow reverse flow under specific conditions. Engineered to handle a maximum operating pressure of up to 5000 psi (350 bar), the DNCALBN914N is robust and reliable. It features a fatigue-rated solenoid tube assembly suitable for demanding applications. This model does not require any minimum hydraulic pressure to operate, enhancing its versatility across various hydraulic setups. The valve incorporates EPDM seals configured specifically for use with phosphate ester fluids; however, these seals are susceptible to damage when exposed to petroleum-based substances. Its wet armature design allows the working fluid to surround the armature, potentially affecting performance if exposed to heat for prolonged periods\u2014particularly relevant when using water-glycol mixtures. Additionally, the DNCALBN914N offers a variety of coil termination and voltage options, including models with surge protection. The solenoid\u2019s efficient magnetic design ensures high spool actuating force per watt expended, facilitating reliable valve shifting. Coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. Various connector options provide up to IP69K ratings for enhanced environmental protection. This valve is built using Sun\u2019s floating style construction which helps prevent internal parts from binding due to excessive installation torque or variations in cavity/cartridge machining. With a swift response time of approximately 50 ms and capable of handling switching frequencies up to 15,000 cycles per hour, the DNCALBN914N is designed for both effectiveness and endurance in rigorous industrial environments.
