The Sun Hydraulics DNCATBN4E24V (DNCATBN4E24V) is a solenoid-operated, 4-way, 2-position cartridge valve designed for direct-acting, balanced spool directional control. It features a closed transition between positions to minimize oil loss during shifting, which is crucial in pilot control circuits. The valve\u2019s capacity is optimized with port 3 as the inlet and port 1 as the tank, although reverse flow is possible but not recommended due to performance limitations. The solenoid tube assembly is fatigue-rated for up to 5000 psi (350 bar), ensuring durability in high-pressure applications. This direct-actuated valve operates without requiring a minimum hydraulic pressure and incorporates EPDM seals for compatibility with phosphate ester fluids while being susceptible to damage from petroleum-based substances. The DNCATBN4E24V utilizes a wet armature design that allows the working fluid to cool the armature and coil, though prolonged energization can lead to fluid breakdown in certain mixtures like water-glycol. A variety of coil termination and voltage options are available, enhancing adaptability with or without surge protection. The solenoid's magnetic design provides high efficiency by maximizing spool actuating force per watt expended, resulting in reliable operation. Coils are interchangeable within Sun Series 1 solenoid products and can be mounted bidirectionally on the tube. This model supports IP69K-rated coil connector options for enhanced environmental protection and employs Sun's floating style construction to reduce internal part binding risks due to excessive torque or machining variations. With a cavity T-31A and series 1 designation, it offers an 8 gpm (30 L/min) capacity with a maximum operating pressure of 5000 psi (350 bar). It has a typical response time of 50 ms and supports up to 15,000 cycles per hour switching frequency. The manual override requires minimal force and stroke for operation, while installation torque ranges between 30-35 lbf ft (41-47 Nm).
