The Sun Hydraulics DMDAXBN528 (DMDAXBN528) is a solenoid-operated, 3-way, 2-position cartridge valve that stands out for its direct-acting, balanced spool directional control. Designed to be fatigue rated for service up to 5000 psi (350 bar), this valve is optimal for high-pressure applications. The spools B and R maintain a closed transition between their two positions, enhancing performance by ensuring faster and more consistent response times, particularly suitable for pilot controls where capacity is less critical. This model is directly actuated and operates without requiring a minimum hydraulic pressure, adding to its versatility in various system configurations. It features manual override options with the D or L control having a detent mechanism intended for temporary actuation. The mechanical life expectancy of the manual control assembly in models equipped with D, L, and T controls is around 7,000 cycles. The valve employs EPDM seals configured specifically for use with phosphate ester fluids; however, these seals are susceptible to damage if exposed to petroleum-based fluids. It also incorporates a wet armature design where the working fluid surrounds the armature which could be subject to heat during prolonged coil energization \u2014 an important consideration in fluid selection. Additionally, the interchangeable coils compatible with other Sun Series 1 solenoid products offer flexibility in mounting and maintenance. The design includes Sun\u2019s floating style construction which minimizes internal parts binding that could occur due to excessive installation torque or cavity/cartridge machining variations. With a switching frequency of 15,000 cycles/hr and typical response times of 50 ms, this valve ensures reliable operation under demanding conditions. It supports up to 12 gpm (45 L/min) capacity making it suitable for a variety of hydraulic applications requiring precise directional control and rapid switching capabilities.
