The Sun Hydraulics DMDALBV912N (DMDALBV912N) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for robust hydraulic control in various applications. This direct-acting, balanced spool directional valve features a fatigue rating of 5000 psi (350 bar), making it suitable for high-pressure environments. The unique design includes closed transitions between Spools B and R, enhancing performance by ensuring faster and more consistent response times, particularly beneficial in pilot control setups where capacity is less critical. The valve operates without the need for minimum hydraulic pressure, adding to its versatility and ease of use across different hydraulic systems. It also features manual override options with a detent mechanism specifically designed for temporary actuation; these include models equipped with D or L control, supporting up to approximately 7,000 cycles of mechanical life expectancy. Additionally, the DMDALBV912N is engineered with EPDM seals intended for use with phosphate ester fluids; however, these seals must not be exposed to petroleum-based fluids as they can cause damage. The wet armature design of the valve ensures that the working fluid surrounds the armature which could be a consideration if the coil remains energized over extended periods due to potential breakdowns in certain fluid types like water-glycol mixtures. For enhanced compatibility and maintenance ease, the coils of this model are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. The construction incorporates Sun\u2019s floating style to minimize internal binding caused by excessive installation torque or variations in cavity/cartridge machining. This model supports up to 12 gpm (45 L/min) capacity and has a rapid typical response time of 50 ms. It is designed with a focus on reliability and consistent operational quality across various hydraulic applications.
