The Sun Hydraulics DMDATPV528 (DMDATPV528) is a solenoid-operated 3-way, 2-position cartridge that functions as a direct-acting, balanced spool directional valve. Engineered for high-performance applications, this valve features a fatigue rating suitable for 5000 psi (350 bar) service, making it robust for demanding operational conditions. The DMDATPV528 is designed with closed transitions between its two positions on Spools B and R, enhancing performance by ensuring faster and more consistent response times, particularly useful in pilot control applications where capacity is less critical. This model operates without requiring a minimum hydraulic pressure, adding to its versatility across various hydraulic systems. It includes options such as manual overrides with detent mechanisms (designated by D or L control), which are intended for temporary actuation and have a mechanical life expectancy of around 7,000 cycles. The valve also supports EPDM seals configured specifically for use with phosphate ester fluids; however, these seals must be shielded from exposure to petroleum-based substances to prevent damage. Additionally, the DMDATPV528 incorporates a wet armature design wherein the working fluid envelops the armature\u2014this design consideration is crucial when the coil remains energized over extended periods as it impacts fluid integrity due to heat exposure. Compatibility with other Sun Series 1 solenoid products allows interchangeable coils that can be mounted in either direction on the tube. Moreover, the construction of this model uses Sun's floating style to minimize internal parts binding caused by excessive installation torque or variations in cavity/cartridge machining. With features like a maximum flow capacity of 12 gpm (45 L/min) and quick response time typically around 50 ms, along with an ability to handle switching frequencies up to 15,000 cycles per hour, the DMDATPV528 proves essential for efficient hydraulic system management where reliability and precision are paramount.
