The Sun Hydraulics DMDAMNV71219 (DMDAMNV71219) is a solenoid-operated 3-way, 2-position cartridge valve, designed for high-performance hydraulic systems. This direct-acting, balanced spool directional valve is notable for its robust construction, including a fatigue-rated solenoid tube assembly suitable for service up to 5000 psi (350 bar). The DMDAMNV71219 features closed transitions between Spools B and R, optimizing performance by ensuring faster and more consistent response times, particularly suitable for pilot control applications where capacity is less critical. This versatile valve does not require a minimum hydraulic pressure to operate, making it highly effective in various operational scenarios. It includes options such as the D or L control with a detent mechanism in the manual override intended for temporary actuation. The mechanical life expectancy of the manual control assembly is approximately 7,000 cycles. Additionally, this model uses EPDM seals designed specifically for systems utilizing phosphate ester fluids; however, these seals are susceptible to damage from exposure to petroleum-based fluids. The DMDAMNV71219 also employs a wet armature design allowing the working fluid to surround the armature which can be significant if the coil remains energized over extended periods. This model supports an interchangeable coil system compatible with other Sun Series 1 solenoid products and can be mounted in either orientation on the tube. It also incorporates Sun\u2019s floating style construction that minimizes internal parts binding due to installation torque or machining variations of cavity/cartridge. With specifications like a maximum flow capacity of 12 gpm (45 L/min), typical response time of 50 ms, and maximum operating pressure of 5000 psi (350 bar), this valve is engineered for efficiency and reliability in demanding applications.
