The Sun Hydraulics DMDAXNN536 (Material Number DMDAXNN536) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for precise control in hydraulic systems. It features a direct-acting, balanced spool directional valve mechanism that operates without the need for minimum hydraulic pressure, enhancing its responsiveness and reliability under various operating conditions. The valve is equipped with a fatigue-rated solenoid tube assembly capable of handling pressures up to 5000 psi (350 bar), making it suitable for rigorous industrial applications. This model incorporates closed transitions between spool positions B and R, optimizing performance by allowing faster and more consistent response times, particularly beneficial in pilot control applications where capacity is less critical. The manual override feature found in models with D or L control uses a detent mechanism intended for temporary actuation, with a mechanical life expectancy of about 7,000 cycles. The DMDAXNN536 utilizes EPDM seals specifically for compatibility with phosphate ester fluids; however, these seals are susceptible to damage if exposed to petroleum-based fluids. Its wet armature design means the working fluid surrounds the armature which could lead to breakdowns in certain fluid types like water-glycol mixtures due to heat exposure over prolonged periods. Additionally, the valve supports interchangeable coils from other Sun Series 1 solenoid products and can be installed in either direction on the tube. It also features Sun's floating style construction which minimizes internal part binding caused by excessive installation torque or cavity/cartridge machining variations. With a flow capacity of up to 12 gpm (45 L/min) and rapid response times typically around 50 ms, this valve ensures efficient operation and leak protection at high pressures up to 3000 psi (210 bar) with maximum leakage specifications of 5 in\u00b3/min.
