The Sun Hydraulics DMDADAN814N (DMDADAN814N) is a high-performance solenoid-operated 3-way, 2-position cartridge valve, designed for direct-acting and balanced spool directional control. With a robust construction that is fatigue rated for up to 5000 psi (350 bar), this valve ensures reliable operation in demanding applications. Its unique design features closed transitions between Spools B and R, optimizing performance by providing faster and more consistent response times particularly suitable for pilot control applications where capacity is less critical. The DMDADAN814N operates without requiring a minimum hydraulic pressure, enhancing its versatility across various hydraulic systems. It also includes manual override options with D, L, or T control setups, where the detent mechanism supports temporary actuation with a mechanical life expectancy of around 7,000 cycles. This model is equipped with EPDM seals suitable for phosphate ester fluids; however, it should not be exposed to petroleum-based fluids as they can damage the seals. This valve employs a wet armature design allowing the working fluid to surround the armature which might affect fluid integrity under prolonged energization. It supports interchangeable coils with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. Furthermore, it incorporates Sun's floating style construction which minimizes internal parts binding due to excessive installation torque or cavity/cartridge machining variations. Key specifications include a flow capacity of 12 gpm (45 L/min), maximum operating pressure of 5000 psi (350 bar), typical response time of 50 ms, and maximum leakage at 3000 psi rated at about 5 in\u00b3/min. The valve also features manual override capabilities requiring minimal force and stroke distances that ensure ease of manual operation when necessary.
