The Sun Hydraulics DNDATXN612 (DNDATXN612) is a solenoid-operated, 4-way, 2-position cartridge valve designed for direct-acting applications. This balanced spool directional valve operates efficiently with no minimum hydraulic pressure required, thanks to its direct actuation. The solenoid tube assembly is fatigue-rated for service pressures up to 5000 psi (350 bar), ensuring reliability under demanding conditions. It features a wet armature design, which allows the working fluid to surround the armature, helping dissipate heat generated by the coil. However, this design requires consideration of fluid type and exposure duration due to potential breakdown in certain fluids like water-glycol mixtures. The valve offers various manual override options, including configurations without manual override. For models equipped with D or L control options, the detent mechanism in the manual override is intended for temporary actuation and has a mechanical life expectancy of approximately 7,000 cycles. The DNDATXN612 is compatible with systems using phosphate ester fluids when equipped with EPDM seals; however, exposure to petroleum-based fluids should be avoided as it can damage these seals. Interchangeable coils from Sun Series 1 solenoid products can be mounted in either direction on the tube and are available with different termination and voltage options, some offering surge protection and environmental ratings up to IP69K. The unique magnetic design of the solenoid contributes to high efficiency and reliable valve shifting by maximizing spool actuating force per watt expended. This cartridge fits into a T-31A cavity and handles capacities up to 10 gpm (40 L/min). It features a typical response time of 50 ms and supports a switching frequency of up to 15,000 cycles per hour. With minimal internal leakage at specified conditions and robust construction minimizing binding risks during installation or machining variations, this valve offers dependable performance for various hydraulic applications.
