The Sun Hydraulics DNDATYN828 (DNDATYN828) is a solenoid-operated, 4-way, 2-position cartridge valve designed for high-performance directional control in hydraulic systems. This direct-acting, balanced spool directional valve operates without needing a minimum hydraulic pressure, making it versatile for various applications. The solenoid tube assembly is fatigue-rated for service up to 5000 psi (350 bar), ensuring durability and reliability under demanding conditions. The valve features multiple manual override options, though it's important to note that manual override functionality is incompatible with weatherized coils. Models equipped with the D or L control offer a detent mechanism for temporary actuation with a mechanical life expectancy of approximately 7,000 cycles. The cartridge is compatible with EPDM seals for systems using phosphate ester fluids but should avoid petroleum-based fluids which can damage the seals. Utilizing a wet armature design, the working fluid surrounds the armature and manages heat generated by the coil during extended energization periods. This can affect fluid stability over time, particularly in water-glycol mixtures. The valve offers a variety of coil termination and voltage options, some with surge protection, enhancing adaptability to specific system requirements. The solenoid's magnetic design ensures high efficiency by providing substantial spool actuating force per watt expended, contributing to reliable valve shifting performance. Coils are interchangeable with other Sun Series 1 solenoid products and can be mounted bidirectionally on the tube. Coil connector options are available with ratings up to IP69K for enhanced environmental protection. Notably incorporating Sun's floating style construction minimizes potential internal part binding due to excessive installation torque or machining variations within cavity/cartridge interfaces. With a capacity of 10 gpm (40 L/min), response time typically at 50 ms, and maximum leakage at 10 in\u00b3/min (160 cc/min) at 3000 psi (210 bar), this valve is robustly engineered for efficient operation in demanding hydraulic applications.
