The Sun Hydraulics DNCATJN514 (DNCATJN514) is a solenoid-operated, 4-way, 2-position cartridge valve known for its direct-acting, balanced spool directional function. It features a closed transition between positions, significantly reducing oil loss during shifts, which is crucial for pilot control circuits. The valve's capacity is optimized with port 3 as the inlet and port 1 as the tank; however, reverse flow isn't recommended due to potential performance issues. Designed for high-pressure applications, this valve's solenoid tube assembly is fatigue-rated for service up to 5000 psi (350 bar). It operates without needing a minimum hydraulic pressure and utilizes EPDM seals compatible with phosphate ester fluids while being vulnerable to petroleum-based substances. The DNCATJN514 employs a wet armature design where the working fluid surrounds and cools the armature. This is important when the coil remains energized for extended periods since certain fluids may degrade at elevated temperatures, potentially affecting functionality. The product offers various coil termination and voltage options with or without surge protection. Its efficient magnetic design ensures high spool actuating force per watt expended, providing reliable shifting capabilities. Compatible with other Sun Series 1 solenoid products, its interchangeable coils can be mounted in any direction on the tube. Coil connector options are available with ratings up to IP69K for enhanced environmental protection. The valve incorporates Sun's floating style construction to mitigate risks of internal binding due to excessive installation torque or machining variations in cavity/cartridge designs. Additional specifications include a capacity of 8 gpm (30 L/min), typical response time of 50 ms, maximum leakage of 10 in\u00b3/min at 110 SUS (24 cSt) and 3000 psi (210 bar), and a switching frequency of up to 15000 cycles/hr. The valve requires an installation torque between 30-35 lbf ft (41-47 Nm) and weighs approximately .60 lb (.30 kg).
