The Sun Hydraulics DMDAXPN72419 (DMDAXPN72419) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for robust hydraulic system applications. This direct-acting, balanced spool directional valve operates efficiently with no minimum hydraulic pressure required. It features a fatigue-rated solenoid tube assembly capable of handling up to 5000 psi (350 bar), ensuring durability and reliability in demanding environments. The valve's design includes closed transitions between spools B and R, enhancing performance by providing faster and more consistent response times, especially suitable for pilot controls where capacity is less critical. Additionally, the DMDAXPN72419 incorporates manual override options with a detent mechanism intended for temporary actuation, supporting mechanical life expectancies of approximately 7,000 cycles. This model is compatible with EPDM seals specifically for use with phosphate ester fluids; however, these seals must avoid exposure to petroleum-based fluids which can cause damage. The wet armature design of the valve helps in cooling but requires consideration regarding the type of fluid used due to potential breakdowns at high temperatures. For maintenance and customization, its coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction to suit various installation requirements. Key specifications include a maximum flow capacity of 12 gpm (45 L/min), typical response times of around 50 ms, and a switching frequency up to 15,000 cycles per hour. The DMDAXPN72419 also features Sun's floating style construction which minimizes internal parts binding caused by excessive installation torque or cavity/cartridge machining variations. This makes it an adaptable solution for numerous hydraulic control systems requiring precise flow management and directional control under high-pressure conditions.
