The Sun Hydraulics DMDAMNN712N (DMDAMNN712N) is a high-performance solenoid-operated 3-way, 2-position cartridge valve. It features a direct-acting, balanced spool directional valve design that ensures reliable control in various hydraulic systems. With a maximum operating pressure of 5000 psi (350 bar) and a flow capacity of 12 gpm (45 L/min), this valve is engineered to handle demanding applications efficiently. The DMDAMNN712N incorporates advanced features such as closed transitions between spools B and R, enhancing performance by providing faster and more consistent response times, especially suitable for pilot control applications where capacity is less critical. The valve's wet armature design allows the working fluid to surround the armature, which is beneficial for heat dissipation but requires careful selection of fluids to avoid breakdown and varnish formation. This model also boasts interchangeable coils with other Sun Series 1 solenoid products, adding versatility and ease of maintenance. The manual override feature included in models with D or L control is designed for temporary actuation, with a mechanical life expectancy of about 7,000 cycles. Additionally, it uses EPDM seals specifically for systems with phosphate ester fluids; however, these seals must not be exposed to petroleum-based fluids as they can cause damage. Further ensuring durability and reliability, the DMDAMNN712N features Sun's floating style construction which minimizes internal parts binding due to excessive installation torque or cavity/cartridge machining variations. This robust construction along with precise engineering makes the Sun Hydraulics DMDAMNN712N an essential component for efficient hydraulic system operations across various applications.
