The Sun Hydraulics DMDAMBN212N (DMDAMBN212N) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for precise hydraulic control. This direct-acting, balanced spool directional valve is engineered to operate efficiently with a maximum operating pressure of 5000 psi (350 bar) and has a flow capacity of up to 12 gpm (45 L/min). The model features closed transitions between spools B and R, enhancing performance by providing faster and more consistent response times, particularly beneficial in pilot control applications where capacity is less critical. The DMDAMBN212N incorporates a wet armature design, allowing the working fluid to surround the armature which helps in managing the heat generated by the coil. However, this design requires consideration of fluid compatibility as certain fluids like water-glycol mixtures may degrade under prolonged exposure to heat. The valve is designed for fatigue-rated service at 5000 psi, ensuring durability and reliability under demanding conditions. Furthermore, this model supports interchangeable coils with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. It also features Sun's floating style construction which minimizes internal parts binding due to excessive installation torque or variations in cavity/cartridge machining. Manual override options are available with a mechanical life expectancy of about 7,000 cycles for temporary actuation needs. This valve is particularly suited for systems using phosphate ester fluids as it can be configured with EPDM seals specifically designed for such applications; however, exposure to petroleum-based fluids should be avoided as it can damage these seals. The manual override requires minimal force and offers precise control over the valve operation. Overall, the DMDAMBN212N is an effective solution for advanced hydraulic systems requiring robust performance and high reliability.
