The Sun Hydraulics DMDADPV748 (DMDADPV748) is a high-performance solenoid-operated 3-way, 2-position cartridge valve. Designed for direct-acting operation, this balanced spool directional valve does not require minimum hydraulic pressure to function. It features a robust solenoid tube assembly that is fatigue rated for service up to 5000 psi (350 bar), making it suitable for high-pressure applications. This model's design includes closed transitions between Spools B and R, enhancing performance by providing faster and more consistent response times in pilot control applications where capacity is less critical. The manual override feature equipped with D or L control offers a detent mechanism intended for temporary actuation, with a mechanical life expectancy of approximately 7,000 cycles. The DMDADPV748 utilizes EPDM seals specifically for use with phosphate ester fluids; however, these seals are susceptible to damage if exposed to petroleum-based fluids. Its wet armature design allows the working fluid to surround the armature, which can be a consideration if the coil remains energized over extended periods due to potential breakdown of certain fluids like water-glycol mixtures. Interchangeability of coils with other Sun Series 1 solenoid products adds versatility, as they can be mounted in either direction on the tube. This valve also incorporates Sun's floating style construction which helps minimize internal parts binding caused by excessive installation torque or variations in cavity/cartridge machining. With a maximum operating pressure of 5000 psi and capable of handling up to 12 gpm (45 L/min), the DMDADPV748 provides reliable performance under demanding conditions. Its quick response time (typically 50 ms), low leakage rate at high pressures, and capability of switching up to 15,000 cycles per hour make it an effective solution for various fluid power applications requiring precise control and durability.
