The Sun Hydraulics DNCADTN812 (DNCADTN812) is a high-performance, solenoid-operated, 4-way, 2-position cartridge valve. This direct-acting, balanced spool directional valve is designed with a closed transition between positions, significantly reducing oil loss during shifting which is crucial in pilot control circuits. The valve operates effectively with a capacity based on port 3 as the inlet and port 1 as the tank, although it supports reverse flow, optimal performance in this mode isn't guaranteed. Engineered for durability and reliability, the DNCADTN812 features a solenoid tube assembly that is fatigue rated for service up to 5000 psi (350 bar). It requires no minimum hydraulic pressure to operate and incorporates EPDM seals suitable for systems using phosphate ester fluids; however, these seals are susceptible to damage if exposed to petroleum-based substances. The wet armature design of the valve ensures that the working fluid surrounds the armature\u2014important for heat management when the coil is energized over long periods. The DNCADTN812 offers various coil termination and voltage options including configurations with surge protection. Its magnetic design enhances solenoid efficiency providing strong spool actuating force per watt of power consumed. Coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. Additional features include environmental protection options like weatherized coils and kits, and Sun's floating style construction which minimizes internal parts binding. This model fits within a T31A cavity and belongs to Series 1 with specifications including an 8 gpm (30 L/min) capacity and maximum operating pressure of 5000 psi (350 bar). The response time is typically around 50 ms with maximum leakage at high pressure noted at approximately 10 in\u00b3/min at 3000 psi. Designed for robust performance in demanding applications, it also offers manual override capabilities and various installation features ensuring ease of use and maintenance.
