The Sun Hydraulics DMDAMBN4E12V (DMDAMBN4E12V) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve designed for rigorous hydraulic applications. This direct-acting, balanced spool directional valve boasts a robust construction, featuring a solenoid tube assembly that is fatigue rated for 5000 psi (350 bar) service, ensuring reliable operation under high-pressure conditions. The valve's unique design includes closed transitions between Spools B and R, optimizing performance by providing faster and more consistent response times in pilot control applications where capacity is less critical. This model operates without the need for minimum hydraulic pressure, facilitating its use in a variety of settings with diverse operational demands. It includes options for manual override controls (D, L, and T types), which are primarily intended for temporary actuation with a mechanical life expectancy of around 7,000 cycles. The DMDAMBN4E12V is compatible with EPDM seals suitable for systems using phosphate ester fluids; however, these seals must avoid contact with petroleum-based fluids to prevent damage. Another notable feature of this valve is its wet armature design that allows the working fluid to surround the armature. This design can influence fluid integrity if the coil remains energized excessively, potentially leading to breakdowns in certain fluid types like water-glycol mixtures. For versatility in installation and maintenance, the coils of this model are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. Additional specifications include a maximum operating pressure of 5000 psi (350 bar), flow capacity up to 12 gpm (45 L/min), and typical response times as swift as 50 ms. With its robust construction and adaptable features, the DMDAMBN4E12V offers an effective solution for controlling fluid power in various hydraulic systems while maintaining high reliability and performance standards.
