The Sun Hydraulics DMDAMAN72419 (DMDAMAN72419) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for precise hydraulic control. This direct-acting, balanced spool directional valve is engineered to operate without a minimum hydraulic pressure requirement, making it highly effective in various applications. The valve features a fatigue-rated solenoid tube assembly capable of handling services up to 5000 psi (350 bar), ensuring durability and reliability under high-pressure conditions. With spools B and R closed during the transition between positions, the DMDAMAN72419 achieves superior performance by providing faster and more consistent response times, ideal for use as pilot controls where capacity is less critical. The valve's wet armature design allows the working fluid to surround the armature, which is beneficial for heat dissipation but requires consideration regarding fluid selection as some may degrade at higher temperatures. This model also supports interchangeable coils with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. It incorporates Sun's floating style construction to reduce internal parts binding caused by excessive installation torque or cavity/cartridge machining variations. Additionally, the manual override feature with a detent mechanism is designed for temporary actuation only, with a mechanical life expectancy of about 7,000 cycles. The DMDAMAN72419 offers a flow capacity of up to 12 gpm (45 L/min) and features rapid response times typically around 50 ms. It also maintains maximum valve leakage at 5 in\u00b3/min at 3000 psi (80 cc/min at 210 bar) and can handle switching frequencies up to 15,000 cycles per hour. This model is particularly suited for systems using phosphate ester fluids due to its EPDM seal configuration; however, exposure to petroleum-based fluids should be avoided as it can damage the seals.
