The Sun Hydraulics DMDALBV828 (DMDALBV828) 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 notable for its closed transition between Spools B and R, enhancing performance by providing faster and more consistent response times, particularly suitable for pilot control applications where capacity is less critical. The valve operates without requiring a minimum hydraulic pressure, making it versatile for various operational environments. Engineered to handle a maximum operating pressure of 5000 psi (350 bar) and a flow capacity of up to 12 gpm (45 L/min), the DMDALBV828 ensures reliable control in demanding conditions. It features a fatigue-rated solenoid tube assembly specifically designed for high-pressure service up to 5000 psi. The manual override option includes a detent mechanism intended for temporary actuation with an estimated mechanical life of around 7,000 cycles. The valve incorporates EPDM seals suitable for systems using phosphate ester fluids; however, these seals must avoid exposure to petroleum-based fluids which can cause damage. Its wet armature design allows the working fluid to surround the armature, which could be significant if the coil remains energized over extended periods due to potential breakdowns in certain fluid types like water-glycol mixtures. Additionally, this model uses interchangeable coils compatible with other Sun Series 1 solenoid products and features Sun\u2019s floating style construction that minimizes internal part binding caused by excessive installation torque or variations in cavity/cartridge machining. This design consideration helps maintain operational integrity and reliability across various installation scenarios.
