The Sun Hydraulics DNCADAN836 (DNCADAN836) 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, significantly 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, although it allows for reverse flow under certain conditions. Rated for up to 5000 psi (350 bar), the solenoid tube assembly of this valve is fatigue rated, ensuring durability and reliability under high pressure conditions. It operates without requiring a minimum hydraulic pressure, enhancing its versatility across various applications. The DNCADAN836 incorporates EPDM seals specifically for use with phosphate ester fluids; however, these seals are susceptible to damage if exposed to petroleum-based substances. This model employs a wet armature design where the working fluid surrounds the armature. This arrangement necessitates consideration of fluid type as some, like water-glycol mixtures, may degrade at higher temperatures due to prolonged coil energization. The DNCADAN836 offers an array of coil termination and voltage options including models with surge protection. Its coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. Additional features include a variety of environmental protection options with weatherized coils and kits available for enhanced durability against elements. The design also includes Sun's floating style construction which helps prevent internal parts binding that could result from excessive installation torque or variations in cavity/cartridge machining. This model offers robust performance specifications including a maximum operating pressure of 5000 psi (350 bar), flow capacity up to 8 gpm (30 L/min), and rapid response times typical at 50 ms.
