The Sun Hydraulics DNDAMXE72419 (DNDAMXE72419) is a solenoid-operated 4-way, 2-position cartridge valve designed for direct-acting, balanced spool directional control. This valve is engineered to operate efficiently without requiring a minimum hydraulic pressure, making it versatile for various applications. It features a fatigue-rated solenoid tube assembly capable of handling up to 5000 psi (350 bar), ensuring reliability under high-pressure conditions. The cartridge offers multiple manual override options, though these are not compatible with weatherized coils. Models with D or L control include a detent mechanism meant for temporary actuation, with an estimated mechanical life of around 7,000 cycles. The valve incorporates a wet armature design that allows the working fluid to surround the armature, potentially impacting function if the coil is energized for extended periods due to heat exposure. Fluids like water-glycol mixtures may degrade over time at elevated temperatures. The DNDAMXE72419 provides various coil termination and voltage options with optional surge protection, enhancing its adaptability across different systems. Its high-efficiency solenoid design delivers substantial spool actuating force per watt expended, promoting dependable valve shifting. This model supports interchangeable coils compatible with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. Coil connector options offer protection ratings up to IP69K, and additional weatherized kits are available for enhanced environmental resilience. The valve's construction minimizes internal part binding from excessive torque or machining variations due to its floating style design. Key specifications include a capacity of 10 gpm (40 L/min), response time of approximately 50 ms, maximum leakage of 10 in/min at 3000 psi (160 cc/min at 210 bar), and a switching frequency of up to 15,000 cycles per hour. The cartridge has a seal kit option using Viton material for compatibility with specific fluids.
