The Sun Hydraulics DMDATPV514 (DMDATPV514) is a solenoid-operated 3-way, 2-position cartridge valve designed for precise control in hydraulic systems. This direct-acting, balanced spool directional valve operates without the need for a minimum hydraulic pressure, enhancing its reliability and performance across various applications. The valve features a fatigue-rated solenoid tube assembly capable of handling pressures up to 5000 psi (350 bar), making it suitable for high-pressure environments. One of the distinctive aspects of the DMDATPV514 is its closed transition between Spools B and R, which ensures higher performance by reducing capacity only when switching states. This feature is particularly beneficial in pilot control applications where rapid and consistent response times are critical. The manual override option, available with D or L control models, includes a detent mechanism designed for temporary actuation with a mechanical life expectancy of about 7,000 cycles. The valve is equipped with EPDM seals configured specifically for use with phosphate ester fluids; however, these seals are susceptible to damage if exposed to petroleum-based substances. Additionally, its wet armature design means that the working fluid surrounds the armature which could be a concern if the coil remains energized extensively as it leads to heat generation that might degrade certain fluid types. Interchangeability of coils with other Sun Series 1 solenoid products adds versatility to this model, allowing for easy maintenance and replacement. The construction incorporates Sun's floating style to minimize internal parts binding caused by excessive installation torque or cavity/cartridge machining variations. With a maximum flow capacity of 12 gpm (45 L/min) and swift response time typically around 50 ms, the DMDATPV514 is an efficient solution for managing directional control in advanced hydraulic systems.
