The Sun Hydraulics DNCADJV628 (DNCADJV628) is a high-performance, solenoid-operated, 4-way, 2-position cartridge valve. This direct-acting, balanced spool directional valve features a closed transition between positions to minimize oil loss during shifting, making it particularly valuable in pilot control circuits. With a capacity of 8 gpm/30 L/min based on port 3 as the inlet and port 1 as the tank, the DNCADJV628 ensures efficient flow management. Although reverse flow is possible through this configuration, optimal performance in this manner isn't guaranteed. The valve's solenoid tube assembly is designed to withstand pressures up to 5000 psi (350 bar), and it operates without requiring a minimum hydraulic pressure, enhancing its versatility across various applications. The DNCADJV628 uses EPDM seals specifically for systems with phosphate ester fluids; however, these seals are susceptible to damage when exposed to petroleum-based fluids. This model incorporates a wet armature design where the working fluid surrounds the armature. Prolonged energization of the coil could lead to fluid degradation if heat dissipates into water-glycol mixtures or similar fluids. For customization and specific application needs, Sun Hydraulics offers a variety of coil termination and voltage options including models with surge protection. Notably efficient due to its unique magnetic design, the DNCADJV628 provides strong spool actuating force per watt expended which assures reliable valve shifting. The interchangeable coils compatible with other Sun Series 1 solenoid products add to its flexibility in use. Additional features like IP69K rated coil connector options and weatherized coils enhance its operational reliability under diverse environmental conditions. Equipped with Sun's floating style construction, this valve minimizes internal parts binding that might occur due to excessive installation torque or machining variations in cavity/cartridge setups. This feature ensures consistent performance and longevity of the component within hydraulic systems.
