The Sun Hydraulics DNCADAV228 (DNCADAV228) 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 features a closed transition between positions, minimizing oil loss during shifting which is particularly beneficial in pilot control circuits. The valve's capacity is optimized with port 3 as the inlet and port 1 as the tank return, although it allows reverse flow under certain conditions. Engineered to operate without minimum hydraulic pressure, the DNCADAV228 can handle a maximum operating pressure of 5000 psi (350 bar) and has a flow capacity of up to 8 gpm (30 L/min). Its solenoid tube assembly is fatigue rated for high-pressure service up to 5000 psi. The use of EPDM seals makes this valve suitable for systems utilizing phosphate ester fluids; however, exposure to petroleum-based fluids should be avoided as it can damage the seals. The DNCADAV228 features a wet armature design where the working fluid surrounds the armature. This design consideration is crucial when the coil is energized for extended periods as some fluids may degrade under heat, affecting performance. With its robust magnetic design, the solenoid provides high efficiency and reliable valve shifting with minimal energy expenditure. It offers a variety of coil termination and voltage options including models with surge protection, and its coils are interchangeable with other Sun Series 1 solenoid products. This model also incorporates Sun's floating style construction which helps prevent internal parts binding due to excessive installation torque or cavity/cartridge machining variations. The valve\u2019s quick response time (typically around 50 ms), along with options for manual override and various environmental protections through additional weatherized coils and kits, make it an adaptable solution for demanding hydraulic applications.
