The Sun Hydraulics DMDATPV928 (DMDATPV928) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve. This direct-acting, balanced spool directional valve is designed to operate seamlessly within a hydraulic system with a maximum operating pressure of 5000 psi (350 bar) and a flow capacity of 12 gpm (45 L/min). The valve features a solenoid tube assembly that is fatigue rated for high-pressure service, ensuring durability and reliability in demanding applications. The DMDATPV928 incorporates closed transitions between spool positions B and R, enhancing performance by providing faster and more consistent response times, particularly suitable for pilot control applications where capacity is less critical. This model is equipped with manual override options including D, L, and T controls; the detent mechanism in these controls supports temporary actuation with a mechanical life expectancy of approximately 7,000 cycles. Designed with versatility in mind, the valve's cartridges configured with EPDM seals are specifically intended for use with phosphate ester fluids. The wet armature design helps manage the heat generated by the coil but requires consideration regarding fluid selection as some may degrade under prolonged exposure to heat. Furthermore, this model benefits from Sun's floating style construction which minimizes internal part binding due to installation torque or cavity/cartridge machining variations. The interchangeable coils compatible with other Sun Series 1 solenoid products add to its flexibility in system design. With additional features like a quick response time of typically 50 ms and minimal maximum valve leakage at high pressures, the DMDATPV928 stands out as an efficient solution for directional control in hydraulic systems.
