The Sun Hydraulics DMDATNN224N (DMDATNN224N) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for precise control in hydraulic systems. This direct-acting, balanced spool directional valve operates without the need for minimum hydraulic pressure, enhancing its versatility across various applications. The valve features a fatigue rating of 5000 psi (350 bar), making it suitable for rigorous industrial use. Key characteristics include closed transitions between Spools B and R, which improve performance limits while reducing capacity\u2014ideal for pilot controls where speed and consistency are critical. The model comes with optional manual override controls (D, L, T) which have a mechanical life expectancy of about 7,000 cycles. The manual override feature is designed specifically for temporary actuation. For environments using phosphate ester fluids, cartridges equipped with EPDM seals are recommended; however, these seals must not be exposed to petroleum-based fluids as they can cause damage. The DMDATNN224N employs a wet armature design allowing the working fluid to cool the armature, although prolonged energization should be monitored as it may degrade certain hydraulic fluids. This valve also supports interchangeable coils with other Sun Series 1 solenoid products and can be installed in any orientation on the tube. It incorporates Sun's floating style construction to minimize internal binding due to installation torque or machining variations of cavity/cartridge. Additional specifications include a maximum flow capacity of 12 gpm (45 L/min), quick response times typically around 50 ms, and robust switching capabilities up to 15,000 cycles per hour. This model's practical design ensures reliable performance and adaptability in complex hydraulic setups.
