The Sun Hydraulics DNDAXTV211 (DNDAXTV211) is a solenoid-operated, 4-way, 2-position cartridge valve designed for direct-acting, balanced spool directional control. It features a solenoid tube assembly that is fatigue-rated for 5000 psi (350 bar) service, ensuring durability and reliability in high-pressure applications. This valve operates without requiring a minimum hydraulic pressure and offers several manual override options, although manual overrides are incompatible with weatherized coils. The DNDAXTV211 employs a wet armature design that allows the working fluid to surround the armature, which can be beneficial or detrimental depending on the fluid type and coil energization duration. It supports various coil termination and voltage configurations with some options offering surge protection. The valve's high-efficiency solenoid design provides significant spool actuating force per watt expended, enhancing reliable valve shifting. The DNDAXTV211 is compatible with Sun Series 1 solenoid products, allowing interchangeable coils that can be mounted in either direction. It also offers coil connector options rated up to IP69K for comprehensive environmental protection. The valve incorporates Sun's floating style construction to minimize internal part binding due to installation torque or machining variations. With a cavity size of T31A and a series designation of 1, it has a capacity of 10 gpm (40 L/min) and an operating pressure up to 5000 psi (350 bar). The typical response time is around 50 ms, with maximum valve leakage at specified conditions being 10 in\u00b3/min at 3000 psi (160 cc/min at 210 bar). It can handle switching frequencies up to 15,000 cycles per hour. The manual override requires a force of approximately 5 lbs/1000 psi at Port 1 and has an override stroke of .10 inches (2.5 mm). The solenoid tube diameter is .75 inches (19 mm), with a hex size of .78 inches (22.2 mm), and it requires an installation torque between 30-35 lbf ft (41-47 Nm). The model weighs approximately .60 lb (.30 kg) and includes Viton seal kits for both cartridge and coil components.
