The Sun Hydraulics DNCATBN624 (DNCATBN624) is a solenoid-operated, 4-way, 2-position cartridge valve featuring a direct-acting, balanced spool directional mechanism. This valve is designed with a closed transition between positions, which significantly minimizes oil loss during shifting\u2014an essential feature for pilot control circuits. The valve's capacity considers port 3 as the inlet and port 1 as the tank; although reverse flow is possible, it is not recommended due to potential performance issues. This robust valve operates efficiently at pressures up to 5000 psi (350 bar) and does not require any minimum hydraulic pressure for operation, thanks to its direct actuation. Constructed with a wet armature design, the working fluid surrounds the armature, exposing it to coil-generated heat. This characteristic should be considered when using fluids prone to breakdown at elevated temperatures. Notably, EPDM seals in this configuration are suitable for phosphate ester fluids but are vulnerable to petroleum-based substances. A diverse range of coil termination and voltage options are available for this model, including those with surge protection. The DNCATBN624 employs a high-efficiency solenoid that delivers substantial spool actuating force per watt expended, ensuring reliable valve shifting. Coils used in this model are interchangeable within Sun Series 1 solenoid products and can be mounted in either direction on the tube. With coil connector options rated up to IP69K and additional weatherized coils available, this valve offers extensive environmental protection. Incorporating Sun's floating style construction minimizes internal part binding due to excessive installation torque or machining variations in cavity/cartridge interfaces. It boasts an impressive switching frequency of up to 15,000 cycles per hour and features manual override capabilities with specific force requirements and stroke dimensions. The DNCATBN624 is compact yet powerful with an installation torque of 30-35 lbf ft (41-47 Nm) and a weight of just .60 lb (0.30 kg).
