The Sun Hydraulics DMDAMPN71219 (DMDAMPN71219) is a solenoid-operated 3-way, 2-position cartridge valve, designed as a direct-acting, balanced spool directional valve. This high-performance component is characterized by its fatigue rating for 5000 psi (350 bar) service, making it robust for demanding applications. The unique design feature of closed transitions between spools B and R enhances performance by ensuring faster and more consistent response times, particularly beneficial when used as pilot controls where capacity is less critical. This valve operates without requiring a minimum hydraulic pressure, providing flexibility in various system conditions. It includes options for manual override controls (D, L, and T), which are primarily intended for temporary actuation with a mechanical life expectancy of around 7,000 cycles. The DMDAMPN71219 utilizes EPDM seals suitable for phosphate ester fluids but must avoid contact with petroleum-based substances to prevent seal damage. Moreover, the wet armature design of the valve ensures that the working fluid surrounds the armature; however, this necessitates consideration of fluid type as prolonged exposure to heat could degrade certain fluids like water-glycol mixtures. The interchangeable coils compatible with other Sun Series 1 solenoid products add to its versatility in installation and maintenance. Key specifications include a flow capacity of 12 gpm (45 L/min), typical response time of 50 ms, and maximum operating pressure capability of 5000 psi (350 bar). Additionally, it features Sun\u2019s floating style construction which minimizes internal parts binding due to installation torque or machining variations in cavity/cartridge. This makes the DMDAMPN71219 an efficient solution for various hydraulic system applications requiring precise control and reliability.
