The Sun Hydraulics DMDATBV71219 (DMDATBV71219) is a high-performance solenoid-operated 3-way, 2-position cartridge valve that features a direct-acting, balanced spool design. This valve is particularly noted for its robust construction and is fatigue rated for 5000 psi (350 bar) service, making it suitable for demanding applications. The valve\u2019s spool transitions between positions B and R are closed, enhancing performance by ensuring faster and more consistent response times, especially in pilot control applications where capacity is less critical. The DMDATBV71219 operates without requiring a minimum hydraulic pressure, which adds to its versatility in various system configurations. It includes manual override options with a detent mechanism designed for temporary actuation; these models are expected to withstand approximately 7,000 cycles. The valve also supports EPDM seal configurations suitable for systems using phosphate ester fluids; however, these seals must not be exposed to petroleum-based substances to avoid damage. An additional feature of the DMDATBV71219 is its wet armature design where the working fluid surrounds the armature. This design consideration is crucial when the coil remains energized over extended periods as it can affect fluid integrity in certain conditions. The valve\u2019s coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. For installation ease and reliability, this model incorporates Sun\u2019s floating style construction which minimizes internal parts binding caused by excessive installation torque or cavity/cartridge machining variations. Key specifications include a flow capacity of 12 gpm (45 L/min), maximum operating pressure of 5000 psi (350 bar), typical response time of 50 ms, and maximum switching frequency of 15,000 cycles per hour.
