The Sun Hydraulics DNDAXCN924 (DNDAXCN924) 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 up to 5000 psi (350 bar) service, ensuring durability and reliability in high-pressure applications. This valve operates without the need for minimum hydraulic pressure, making it versatile for various systems. It offers several manual override options, although these are not compatible with weatherized coils. The manual control assembly has a mechanical life expectancy of approximately 7,000 cycles and requires a manual override force of 5 lbs at 1000 psi (33 N at 100 bar) at Port 1. The valve incorporates a wet armature design that allows the working fluid to surround the armature, which can be advantageous in terms of heat dissipation but requires consideration when using fluids prone to thermal degradation. The DNDAXCN924 also boasts a high-efficiency solenoid with unique magnetic design, providing significant spool actuating force per watt expended and ensuring reliable valve shifting. It supports various coil termination and voltage options with surge protection availability. Coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. Additionally, coil connector options offer ratings up to IP69K for enhanced environmental protection. The valve utilizes Sun's floating style construction to minimize internal part binding due to excessive installation torque or machining variations in the cavity/cartridge interface. The cartridge fits into a T-31A cavity and belongs to Series 1 with a capacity of up to 10 gpm (40 L/min). It has a typical response time of 50 ms and can handle switching frequencies up to 15,000 cycles per hour. Maximum valve leakage is rated at 10 in\u00b3/min at 3000 psi (160 cc/min at 210 bar). The compact design includes dimensions such as a solenoid tube diameter of .75 inches (19 mm), valve hex size of .78 inches (22.2 mm), and an installation torque requirement between 30\u201335 lbf\u00b7ft (41\u201347 Nm).
