The Sun Hydraulics DMDADNV812 (DMDADNV812) is a solenoid-operated 3-way, 2-position cartridge valve. This direct-acting, balanced spool directional valve is designed for high-performance applications with a fatigue rating for 5000 psi (350 bar) service. It features closed transitions between Spools B and R to enhance performance by providing faster and more consistent response times, especially suitable for pilot control applications where capacity is less critical. The DMDADNV812 requires no minimum hydraulic pressure for operation, making it highly versatile in various hydraulic systems. The manual override options available with the D or L control include a detent mechanism intended for temporary actuation, supporting mechanical life expectancy of approximately 7,000 cycles. Additionally, this model can be configured with EPDM seals specifically for use with phosphate ester fluids; however, these seals must not be exposed to petroleum-based fluids as they can cause damage. A notable feature of this valve is its wet armature design which allows the working fluid to surround the armature. This design aspect needs consideration if the coil remains energized over extended periods since some fluids may degrade under prolonged heat exposure. The interchangeable coils with other Sun Series 1 solenoid products add to its adaptability and ease of use. The construction incorporates Sun\u2019s floating style to minimize internal parts binding caused by excessive installation torque or cavity/cartridge machining variations. With a capacity of 12 gpm (45 L/min) and rapid response times typically around 50 ms, the DMDADNV812 provides efficient flow control in demanding settings.
