The Sun Hydraulics DNDAMXN71219 (DNDAMXN71219) is a solenoid-operated, 4-way, 2-position cartridge valve designed for direct-acting, balanced spool directional control. This versatile valve is built to withstand fatigue with a solenoid tube assembly rated for service at up to 5000 psi (350 bar). It operates without the need for a minimum hydraulic pressure and offers several manual override options, though it's important to note that manual override functionality is incompatible with weatherized coils. For models with D or L control, the detent mechanism in the manual override is intended for temporary actuation and has an approximate mechanical life expectancy of 7,000 cycles. The valve features EPDM seals suitable for systems using phosphate ester fluids but should not be exposed to petroleum-based fluids as they can damage the seals. The wet armature design allows the working fluid to surround the armature, which can impact performance when coils are energized for extended periods due to heat exposure. This factor should be considered especially in systems using water-glycol mixtures that may degrade over time. Offering high efficiency through its unique magnetic design, this solenoid provides reliable valve shifting with high spool actuating force per watt expended. The interchangeable coils are compatible with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. With coil connector options rated up to IP69K and additional weatherized coils available, this product ensures robust environmental protection. The cartridge incorporates Sun's floating style construction to prevent internal part binding due to excessive installation torque or machining variations in cavity/cartridge configurations. The valve has a capacity of 10 gpm (40 L/min) and demonstrates a typical response time of 50 ms. Its maximum leakage rate is specified at 10 in\u00b3/min (160 cc/min) at 3000 psi (210 bar), making it highly efficient and reliable for various applications requiring precise directional control.
