The Sun Hydraulics DMDAMAN212N (DMDAMAN212N) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for precise control in hydraulic systems. This direct-acting, balanced spool directional valve is notable for its robust construction, featuring a solenoid tube assembly that is fatigue rated for service up to 5000 psi (350 bar). The valve offers closed transitions between Spools B and R, optimizing performance by providing faster and more consistent response times ideal for pilot control applications where capacity is less critical. The DMDAMAN212N operates effectively without any minimum hydraulic pressure, enhancing its utility in various applications. It includes options such as manual override controls (D, L, and T models), which are primarily intended for temporary actuation with a mechanical life expectancy of around 7,000 cycles. Additionally, the valve employs EPDM seals suitable for systems using phosphate ester fluids; however, these seals must avoid contact with petroleum-based fluids to prevent damage. This model also utilizes a wet armature design allowing the working fluid to surround the armature which could be significant if the coil remains energized over extended periods. The potential breakdown of certain fluids like water-glycol mixtures at high temperatures should be considered as it may impact the cartridge\u2019s functionality. For compatibility and flexibility in system design, its coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. Incorporating Sun\u2019s floating style construction minimizes internal parts binding due to excessive installation torque or variations in cavity/cartridge machining. With a maximum operating pressure of 5000 psi (350 bar) and a flow capacity of up to 12 gpm (45 L/min), this valve ensures reliable performance under demanding conditions. Its quick response time (typically 50 ms), along with minimal leakage and high switching frequency capabilities makes it an efficient choice for sophisticated hydraulic setups requiring precise control and durability.
