The Sun Hydraulics DMDAXNN924N (DMDAXNN924N) is a high-performance solenoid-operated 3-way, 2-position cartridge valve. This direct-acting, balanced spool directional valve is designed to efficiently control the flow of hydraulic fluids within a system. With its robust construction, the valve is fatigue rated for services up to 5000 psi (350 bar), making it suitable for high-pressure applications. This model features closed transitions between spools B and R, optimizing performance by providing faster and more consistent response times, especially useful in pilot control applications where capacity is less critical. The DMDAXNN924N operates without requiring a minimum hydraulic pressure, enhancing its versatility in various system configurations. Equipped with either D or L control options, the valve includes a detent mechanism in the manual override intended for temporary actuation with a mechanical life expectancy of approximately 7,000 cycles. For environments utilizing phosphate ester fluids, cartridges with EPDM seals are recommended to prevent damage from petroleum-based substances. The innovative wet armature design allows the working fluid to surround the armature which helps manage heat dissipation from the coil; however, prolonged energization should be monitored as it can degrade certain fluid types. The interchangeable coils compatible with other Sun Series 1 solenoid products offer flexibility in maintenance and replacement procedures. Additionally, this model incorporates Sun's floating style construction which minimizes internal parts binding due to installation torque or machining variations of cavity/cartridge. Key specifications include a maximum flow capacity of 12 gpm (45 L/min), typical response time of 50 ms, and maximum switching frequency of 15,000 cycles per hour. The manual override requires minimal force and has a stroke length designed for precise control. This compact yet powerful valve is ideal for advanced hydraulic systems requiring reliable and precise fluid control.
