The Sun Hydraulics DMDATBV812 (DMDATBV812) is a solenoid-operated 3-way, 2-position cartridge valve that excels in applications requiring precise directional control. This direct-acting, balanced spool directional valve is designed with a fatigue-rated solenoid tube assembly for up to 5000 psi or 350 bar service, ensuring robust performance under high-pressure conditions. The valve features closed transitions between Spools B and R, optimizing performance by providing faster and more consistent response times ideal for pilot control applications where capacity is less critical. The DMDATBV812 operates without the need for minimum hydraulic pressure, enhancing its versatility across various fluid power systems. It includes manual override options with a detent mechanism designed for temporary actuation, supporting mechanical life expectancy around 7,000 cycles. For environments using phosphate ester fluids, cartridges with EPDM seals are recommended to avoid damage from petroleum-based substances. This model also incorporates a wet armature design where the working fluid surrounds the armature. Such configuration necessitates consideration of fluid type and operating duration as heat from prolonged coil energization can degrade certain fluids. The interchangeability of coils with other Sun Series 1 solenoid products adds to the flexibility and ease of maintenance. Furthermore, the DMDATBV812 benefits from Sun's floating style construction which minimizes internal part binding due to installation torque or machining variations of cavity/cartridge. Key specifications include a flow capacity of 12 gpm (45 L/min), typical response time of 50 ms, and maximum operating pressure of 5000 psi (350 bar). This valve is an effective solution in systems requiring reliable and precise control in dynamic hydraulic conditions.
