The Sun Hydraulics DMDADAV71219 (DMDADAV71219) is a solenoid-operated 3-way, 2-position cartridge valve designed for high-performance hydraulic systems. This direct-acting, balanced spool directional valve is engineered to operate seamlessly without minimum hydraulic pressure, making it suitable for a variety of applications. It features a fatigue rating of 5000 psi (350 bar), ensuring durability and reliability in demanding environments. The DMDADAV71219 incorporates closed transitions between Spools B and R, enhancing performance by providing faster and more consistent response times, particularly beneficial when used as pilot controls. The manual override options, equipped with the D or L control, include a detent mechanism intended for temporary actuation with a mechanical life expectancy of approximately 7,000 cycles. This model uses EPDM seals specifically designed for systems utilizing phosphate ester fluids; however, these seals are susceptible to damage when exposed to petroleum-based fluids. The wet armature design of the valve helps in cooling but requires consideration regarding the type of fluid used as some may degrade under prolonged exposure to heat. Interchangeable coils from Sun's Series 1 solenoid products can be mounted on this model in either direction, adding to its versatility. The valve also benefits from Sun\u2019s floating style construction which minimizes internal parts binding\u2014this is crucial in preventing operational inconsistencies due to installation torque or cavity/cartridge machining variations. Key specifications include a maximum operating pressure of 5000 psi (350 bar), flow capacity up to 12 gpm (45 L/min), and rapid response times typically around 50 ms. The design also supports up to 15,000 switching cycles per hour and features manual override capabilities requiring minimal force. This compact unit weighs just 0.60 lb (0.30 kg) and is designed for easy integration into various hydraulic circuits.
