The Sun Hydraulics DMDATAN528 (DMDATAN528) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for direct-acting, balanced spool directional control. This robust valve features a fatigue rating of 5000 psi (350 bar), making it suitable for demanding applications. The spools, designated B and R, are closed during the transition between positions to enhance performance limits while sacrificing capacity, which is ideal in pilot control scenarios where rapid and consistent response times are crucial. This direct-actuated valve operates without the need for minimum hydraulic pressure, adding to its versatility across various hydraulic systems. The DMDATAN528 includes options such as manual override controls (D, L, T) with a mechanical life expectancy of about 7,000 cycles. It also offers configurations with EPDM seals specifically designed for use with phosphate ester fluids; however, these seals must avoid exposure to petroleum-based substances to prevent damage. The valve's design incorporates a wet armature setup where the working fluid surrounds the armature \u2014 important to consider if the coil remains energized over extended periods due to potential breakdowns in certain fluids like water-glycol mixtures. For compatibility and maintenance ease, its coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. Additional design features include Sun's floating style construction which minimizes internal parts binding caused by excessive installation torque or cavity/cartridge machining variations. Key specifications include a maximum operating pressure of 5000 psi (350 bar), flow capacity up to 12 gpm (45 L/min), and typical response time of 50 ms. The valve supports switching frequencies up to 15000 cycles per hour and requires manual override force of about 5 lbs at 1000 psi for port operation. With its compact size and weight (.60 lb or .30 kg), this valve is engineered for reliability and efficient performance in specialized hydraulic systems.
