The Sun Hydraulics DMDAXBN512 (DMDAXBN512) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for robust hydraulic system applications. This direct-acting, balanced spool directional valve operates without the need for minimum hydraulic pressure, enhancing its versatility in various operating environments. The valve features a fatigue-rated solenoid tube assembly suitable for up to 5000 psi (350 bar), ensuring reliability under high-pressure conditions. Engineered for precision and durability, the DMDAXBN512 incorporates closed transitions between Spools B and R, optimizing performance by providing faster and more consistent response times, particularly useful in pilot control applications where capacity is less critical. The manual override options available with this model include D or L control types, which are intended for temporary actuation with a mechanical life expectancy of approximately 7,000 cycles. This model also supports interchangeable coils with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. It benefits from Sun\u2019s floating style construction which minimizes internal parts binding due to installation torque or machining variations of the cavity/cartridge. The wet armature design of the valve means that the working fluid surrounds the armature; however, care should be taken as prolonged energization can lead to fluid degradation at high temperatures. With a maximum flow capacity of 12 gpm (45 L/min) and typical response times of 50 ms, this valve is designed for efficient operation. It also features a maximum operating pressure of 5000 psi (350 bar) and allows a switching frequency up to 15000 cycles/hr. The use of EPDM seals makes it suitable for systems utilizing phosphate ester fluids but unsuitable for exposure to petroleum-based fluids which could damage the seals.
