The Sun Hydraulics DNCADJN728 (DNCADJN728) 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 ensures a closed transition between positions, significantly minimizing oil loss during shifting\u2014a critical feature for maintaining efficiency in pilot control circuits. Engineered for robust performance, the DNCADJN728 can handle a maximum operating pressure of 5000 psi (350 bar) and has a flow capacity of up to 8 gpm (30 L/min), based on port 3 as the inlet and port 1 as the tank. The valve's solenoid tube assembly is fatigue rated for high-pressure service, enhancing its durability and lifespan under rigorous conditions. It features a wet armature design where the working fluid surrounds the armature; this design consideration is vital for applications where the coil may be energized for extended periods, potentially affecting fluid integrity due to heat exposure. Users should note that while reverse flow through the valve is possible, optimal performance under such conditions is not guaranteed. Sun Hydraulics has equipped the DNCADJN728 with EPDM seals specifically for use with phosphate ester fluids; however, these seals are susceptible to damage if exposed to petroleum-based fluids. A variety of coil termination and voltage options are available to suit different application needs and environmental conditions. The valve also incorporates Sun's unique magnetic design which enhances solenoid efficiency and reliability in valve shifting. Additional features include interchangeable coils compatible with other Sun Series 1 solenoid products, multiple connector options offering up to IP69K protection, and Sun's floating style construction which reduces risks associated with internal parts binding due to installation or machining variances. This makes the DNCADJN728 an adaptable solution suited for various hydraulic applications requiring precise control and reliability.
