The Sun Hydraulics DMDATRN728 (DMDATRN728) 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 is engineered to operate without minimum hydraulic pressure, enhancing its versatility in various operational conditions. It features a fatigue-rated solenoid tube assembly for services up to 5000 psi (350 bar), ensuring durability and reliability under high-pressure scenarios. The valve\u2019s spools B and R maintain a closed transition between positions, optimizing performance by allowing faster and more consistent response times, particularly suitable for pilot control applications where capacity is less critical. The manual override feature incorporated in the D or L control models is specifically designed for temporary actuation and supports around 7,000 cycles of mechanical life expectancy. With a focus on compatibility and maintenance ease, the DMDATRN728's coils are interchangeable with other Sun Series 1 solenoid products. The valve also employs a wet armature design wherein the working fluid surrounds the armature; this is crucial for applications where the coil may be energized for extended periods. Special attention needs to be given to the fluid type used, as EPDM seals in this model are tailored for phosphate ester fluids and can degrade if exposed to petroleum-based substances. This model also incorporates Sun\u2019s floating style construction which minimizes internal parts binding caused by excessive installation torque or variations in cavity/cartridge machining. With its robust construction, interchangeable components, and optimized design for specific fluid types, the Sun Hydraulics DMDATRN728 offers a reliable solution for directing flow within hydraulic systems efficiently.
