The Sun Hydraulics DNCADTV912 (DNCADTV912) is a high-performance, solenoid-operated, 4-way, 2-position cartridge valve designed for efficient hydraulic flow control. This direct-acting, balanced spool directional valve features a closed transition between positions, minimizing oil loss during shifting which is essential for maintaining the integrity of pilot control circuits. The DNCADTV912 operates effectively with a capacity based on port 3 as the inlet and port 1 as the tank, although it allows reverse flow, optimal performance in this mode is not guaranteed. Engineered for robust operation, the solenoid tube assembly of this valve is fatigue rated for up to 5000 psi (350 bar), ensuring durability under high-pressure conditions. It operates without requiring a minimum hydraulic pressure, adding to its versatility in various system configurations. The DNCADTV912 employs EPDM seals specifically suited for systems using phosphate ester fluids; however, these seals are susceptible to damage when exposed to petroleum-based fluids. The design incorporates a wet armature setup where the working fluid surrounds the armature. This design consideration is crucial when the coil remains energized for extended periods since some fluids may degrade at elevated temperatures. The valve offers a variety of coil termination and voltage options, enhancing its adaptability to different operating environments. Sun Hydraulics has also equipped this model with features like interchangeable coils compatible with other Sun Series 1 solenoid products and multiple connector options that support up to IP69K ratings for enhanced environmental protection. Furthermore, its construction includes Sun's floating style design which helps prevent internal parts binding due to installation stress or cavity/cartridge machining variations. With specifications like an 8 gpm (30 L/min) capacity and quick response times typically around 50 ms, along with maximum operating pressures up to 5000 psi (350 bar), the DNCADTV912 stands out as a reliable choice for controlling hydraulic flow in demanding applications.
