The Sun Hydraulics DNCADBV (DNCADBV) 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, which significantly minimizes oil loss during shifting\u2014a crucial factor in maintaining efficiency and performance in pilot control circuits. The valve's design allows for port 3 to be used as the inlet and port 1 as the tank, although it is capable of reverse flow. Engineered for durability and reliability, the DNCADBV's solenoid tube assembly is fatigue rated for up to 5000 psi (350 bar), ensuring it can withstand demanding applications. It operates without requiring a minimum hydraulic pressure, adding to its versatility across various hydraulic setups. Notably, cartridges with EPDM seals are specifically intended for systems utilizing phosphate ester fluids; however, these should not be exposed to petroleum-based substances to avoid damage. The DNCADBV also incorporates a wet armature design where the working fluid surrounds the armature. This aspect needs consideration as prolonged energization of the coil can lead to fluid degradation at high temperatures. The valve offers an array of coil termination and voltage options, including models with surge protection and others rated up to IP69K for enhanced environmental resilience. Additional features include interchangeable coils compatible with other Sun Series 1 solenoid products, and a floating style construction that reduces risks associated with internal parts binding due to installation errors or cavity/cartridge machining variations. With a switching frequency of up to 15000 cycles per hour and a rapid response time of approximately 50 ms, this model ensures efficient operation under various conditions. The DNCADBV is an ideal solution for sophisticated hydraulic systems requiring robust and precise fluid control.
