The Sun Hydraulics DMDAXRV612N (DMDAXRV612N) is a high-performance solenoid-operated 3-way, 2-position cartridge valve, designed for direct-acting operation with a balanced spool directional control mechanism. This model boasts a robust construction that is fatigue rated for 5000 psi (350 bar) service, ensuring reliability and durability in demanding applications. The valve features closed spools B and R during the transition between positions, enhancing performance limits at the cost of reduced capacity. However, this characteristic is beneficial in pilot control applications where capacity is less critical, offering faster and more consistent response times. The DMDAXRV612N operates without requiring minimum hydraulic pressure, making it versatile for various operational scenarios. It includes manual override options with detent mechanism designated for temporary actuation only; these are available in D or L control models. The mechanical life expectancy of these manual control assemblies is around 7,000 cycles. For environments using phosphate ester fluids, cartridges with EPDM seals are recommended to prevent damage from petroleum-based substances. The valve's wet armature design allows the working fluid to surround the armature which could be subjected to heat if the coil remains energized over extended periods. This model also supports interchangeable coils with other Sun Series 1 solenoid products and features a floating style construction to minimize internal parts binding due to installation torque or cavity/cartridge machining variations. Key specifications include a flow capacity of 12 gpm (45 L/min), maximum operating pressure of 5000 psi (350 bar), typical response time of 50 ms, and maximum valve leakage at 110 SUS (24 cSt) being 5 in\u00b3/min at 3000 psi (80 cc/min at 210 bar). Additionally, it supports up to 15,000 switching cycles per hour and requires a manual override force of about 5 lbs at 1000 psi for port operation.
