The Sun Hydraulics DMDAMAV912 (DMDAMAV912) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve designed for robust hydraulic system applications. This direct-acting, balanced spool directional valve is optimized for use in environments requiring precise control and reliability. The DMDAMAV912 features a fatigue-rated solenoid tube assembly capable of handling pressures up to 5000 psi (350 bar), making it suitable for high-pressure applications. The valve's design includes closed transitions between Spools B and R, enhancing performance by ensuring faster and more consistent response times, particularly useful in pilot control setups where capacity is less critical. It operates without the need for minimum hydraulic pressure, providing flexibility in various operational contexts. Additionally, the model comes with optional manual overrides (D, L, T controls) which include a detent mechanism designed for temporary actuation with a mechanical life expectancy of about 7,000 cycles. Configurations with EPDM seals are available for systems using phosphate ester fluids; however, these should not be exposed to petroleum-based fluids as it could damage the seals. The wet armature design allows the working fluid to surround the armature which could be a consideration if the coil remains energized over extended periods possibly affecting fluid integrity in certain conditions. This valve also boasts interchangeable coils with other Sun Series 1 solenoid products and incorporates Sun's floating style construction to minimize internal part binding due to installation variances or cavity/cartridge machining discrepancies. With a maximum flow capacity of 12 gpm (45 L/min) and swift response times typically around 50 ms, the DMDAMAV912 ensures efficient operation and minimal leakage across demanding applications.
