The Sun Hydraulics DMDAMBN712N (DMDAMBN712N) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve that features a direct-acting, balanced spool design. This valve is specifically engineered to handle demanding applications with its fatigue rating for 5000 psi (350 bar) service, making it suitable for high-pressure environments. The unique design of the spools\u2014closed in the transition between two positions\u2014enhances performance by providing faster and more consistent response times, particularly beneficial when used as pilot controls where capacity is less critical. This model is directly actuated and operates without requiring a minimum hydraulic pressure, offering flexibility in various system configurations. It incorporates a wet armature design where the working fluid surrounds the armature, which can be crucial when considering the type of fluid used due to potential breakdowns at high temperatures. The valve also features interchangeable coils with other Sun Series 1 solenoid products and supports both orientations on the tube, enhancing its versatility. Additional attributes include a manual override option with a detent mechanism designed for temporary actuation and an expected mechanical life of approximately 7,000 cycles. The construction utilizes Sun's floating style to minimize internal parts binding caused by excessive installation torque or variations in cavity/cartridge machining. With a maximum flow capacity of 12 gpm (45 L/min) and quick response times typically around 50 ms, this valve ensures efficient operation under varying conditions. Seal options like EPDM are available for systems using phosphate ester fluids, although exposure to petroleum-based fluids should be avoided to prevent damage to seals.
