The Sun Hydraulics DMDALRV814 (DMDALRV814) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve designed for precise hydraulic fluid direction control in various applications. This direct-acting, balanced spool directional valve operates without requiring a minimum hydraulic pressure, making it highly effective in systems where consistent operation is critical. The valve features a fatigue rating for up to 5000 psi (350 bar), ensuring durability and reliability under high-pressure conditions. The DMDALRV814 incorporates closed transitions between Spools B and R, optimizing performance by providing faster and more consistent response times at the expense of lower flow capacity. This characteristic makes it particularly suitable for pilot control applications where flow capacity is less critical than response speed. Additionally, it includes manual override options with a detent mechanism designed for temporary actuation, supporting manual operations when needed. Engineered with a wet armature design, the DMDALRV814 allows the working fluid to surround the armature which may be subject to heat during prolonged energization of the coil. This design consideration is crucial in applications involving specific fluids like water-glycol mixtures that can degrade under heat. The valve also features interchangeable coils compatible with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. The construction of the DMDALRV814 utilizes Sun\u2019s floating style to minimize internal parts binding caused by excessive installation torque or variations in cavity/cartridge machining. With specifications including a maximum operating pressure of 5000 psi (350 bar), a flow capacity of 12 gpm (45 L/min), and rapid response times typically around 50 ms, this valve ensures efficient performance for demanding hydraulic systems. It also supports switching frequencies up to 15000 cycles/hr and incorporates EPDM seals suitable for phosphate ester fluids but not for petroleum-based fluids.
