The Sun Hydraulics DMDAMAN4E12V (DMDAMAN4E12V) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for precise hydraulic fluid direction control in various applications. This direct-acting, balanced spool directional valve is engineered to operate efficiently with no minimum hydraulic pressure requirement, making it highly suitable for pilot control applications where fast and consistent response times are critical. The valve features a fatigue-rated solenoid tube assembly for services up to 5000 psi (350 bar), ensuring durability and reliability under high-pressure conditions. Equipped with closed transitions between Spools B and R, the DMDAMAN4E12V enhances performance by maintaining higher limits at the expense of lower capacity, which is not a concern in pilot-controlled setups. It also incorporates a wet armature design where the working fluid surrounds the armature, potentially affecting fluid properties if exposed to heat for prolonged periods. Users should note that cartridges with EPDM seals are specifically designed for phosphate ester fluids and should avoid contact with petroleum-based substances to prevent seal damage. The valve supports interchangeable coils from other Sun Series 1 solenoid products and can be mounted in either direction on the tube. It also benefits from Sun's floating style construction which minimizes internal parts binding caused by excessive installation torque or machining variations of cavity/cartridge. The manual override feature in models equipped with D or L control is intended for temporary actuation only, with a mechanical life expectancy of approximately 7,000 cycles. This model has a maximum flow capacity of 12 gpm (45 L/min) and offers rapid response times typically around 50 ms. Its robust design includes features like maximum operating pressure up to 5000 psi (350 bar), switching frequency up to 15,000 cycles/hr, and minimal valve leakage at high pressures. These attributes make the DMDAMAN4E12V an excellent choice for systems requiring reliable and efficient directional control of hydraulic fluids.
