The Sun Hydraulics DNDATLN211 (DNDATLN211) is a solenoid-operated, 4-way, 2-position cartridge valve designed for direct-acting, balanced spool directional control. Engineered with a solenoid tube assembly rated for fatigue at 5000 psi (350 bar), this valve operates without requiring minimum hydraulic pressure. It offers multiple manual override options, including versions without manual override; however, note that manual overrides are incompatible with weatherized coils. The D and L control models feature a detent mechanism for temporary actuation with an estimated mechanical life of about 7,000 cycles. This valve is compatible with systems using phosphate ester fluids when equipped with EPDM seals but should not be exposed to petroleum-based substances. Utilizing a wet armature design, the working fluid surrounds the armature and can be affected by heat from prolonged coil energization, potentially impacting fluid integrity in certain mixtures like water-glycol. The DNDATLN211 provides various coil termination and voltage configurations, some offering surge protection. Its efficient solenoid design enhances spool actuating force per watt for reliable shifting. Coils are interchangeable within Sun Series 1 products and can be mounted bi-directionally on the tube. Connector options support ratings up to IP69K for enhanced environmental protection. The valve incorporates Sun's floating style construction to reduce internal binding risks due to installation torque or machining variations. Technical specifications include a T31A cavity configuration, Series 1 classification, a capacity of 10 gpm (40 L/min), and maximum operating pressure of 5000 psi (350 bar). The typical response time is around 50 milliseconds with maximum leakage at specified conditions being 10 in\u00b3/min at 3000 psi (160 cc/min at 210 bar). It supports switching frequencies up to 15,000 cycles per hour and requires a manual override force of approximately 5 lbs/1000 psi at Port 1. The valve features dimensions such as a solenoid tube diameter of .75 inches (19 mm) and hex size of .78 inches (22.2 mm), weighing .60 lbs (.30 kg).
