The Sun Hydraulics DMDAXAN512 (DMDAXAN512) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve featuring a direct-acting, balanced spool directional mechanism. Engineered for robustness and precision, this valve is designed to operate without minimum hydraulic pressure and incorporates a wet armature design, allowing the working fluid to surround the armature. This configuration is particularly useful in applications where consistent and fast response times are critical. The DMDAXAN512 can handle a maximum operating pressure of 5000 psi (350 bar) and has a flow capacity of up to 12 gpm (45 L/min). Its solenoid tube assembly is fatigue rated for high-pressure service up to 5000 psi, ensuring durability under demanding conditions. The valve's spools (B and R) maintain closed positions during transitions, optimizing performance by providing quicker and more reliable switching actions\u2014ideal for pilot control applications where capacity is less critical than speed. This model also features interchangeable coils with other Sun Series 1 solenoid products, adding versatility in maintenance and replacement processes. The manual override mechanism included in models equipped with D or L control is intended for temporary actuation only, with a mechanical life expectancy of about 7,000 cycles. For environmental resilience, cartridges configured with EPDM seals are suitable for systems using phosphate ester fluids; however, they should not be exposed to petroleum-based fluids which can degrade the seals. Additionally, the valve incorporates Sun's floating style construction which minimizes internal part binding due to installation torque or machining variations of cavity/cartridge. This model\u2019s rapid response time (typically around 50 ms), along with its robust manual override features and minimal leakage rates at high pressures, make it an excellent choice for advanced hydraulic systems requiring reliable directional control under varying operational conditions.
