The Sun Hydraulics DNDAXDN814N (DNDAXDN814N) is a solenoid-operated 4-way, 2-position cartridge valve designed for efficient directional control in hydraulic systems. This direct-acting, balanced spool valve is engineered for high performance without the need for minimum hydraulic pressure. It features a solenoid tube assembly that is fatigue-rated for service pressures up to 5000 psi (350 bar), ensuring durability and reliability in demanding applications. The valve offers multiple manual override options, though it is important to note that manual overrides are not compatible with weatherized coils. For models with D or L control, the detent mechanism in the manual override is intended for temporary actuation and has a mechanical life expectancy of approximately 7,000 cycles. The valve incorporates a wet armature design where the working fluid surrounds the armature, which can be critical if the coil is energized for extended periods. Fluids such as water-glycol mixtures may degrade under these conditions over time. The solenoid's magnetic design ensures high efficiency by maximizing spool actuating force per Watt expended, contributing to reliable valve shifting. This model supports a variety of coil termination and voltage options, with some offering surge protection and IP69K ratings for enhanced environmental protection. Coils are interchangeable with other Sun Series 1 solenoid products and can be mounted bidirectionally on the tube. The cartridge also includes Sun's floating style construction to reduce internal binding risks due to installation torque or machining variations. Technical specifications include a capacity of 10 gpm (40 L/min.), typical response time of 50 ms, and maximum leakage at specified conditions of 10 in\u00b3/min (160 cc/min). It supports switching frequencies up to 15,000 cycles per hour and requires specific manual override force and stroke parameters. The valve's hex size measures .78 inches (22.2 mm), with an installation torque range of 30-35 lbf ft (41-47 Nm).
