The Sun Hydraulics DMDAMRN2E12V (DMDAMRN2E12V) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for precise hydraulic fluid direction control. This direct-acting, balanced spool valve ensures efficient operation with its fatigue-rated solenoid tube assembly for services up to 5000 psi (350 bar). The valve features closed transitions between Spools B and R, enhancing performance by ensuring faster and more consistent response times ideal for pilot control applications where capacity is less critical. With no minimum hydraulic pressure required for operation, the DMDAMRN2E12V provides versatility in various hydraulic systems. It includes manual override options with a detent mechanism designed for temporary actuation, boasting a mechanical life expectancy of about 7,000 cycles. This model also accommodates EPDM seals suitable for phosphate ester fluids; however, these seals must avoid exposure to petroleum-based fluids to prevent damage. Another significant aspect of this valve is its wet armature design, where the working fluid surrounds the armature which can be critical if the coil remains energized over extended periods. This design consideration is crucial when using certain fluids like water-glycol mixtures that may degrade at high temperatures. The interchangeable coils compatible with other Sun Series 1 solenoid products add to the flexibility and ease of use of this valve model. Furthermore, the DMDAMRN2E12V incorporates Sun's floating style construction that minimizes internal parts binding caused by excessive installation torque or variations in cavity/cartridge machining. With a maximum flow capacity of 12 gpm (45 L/min) and quick response time typically around 50 ms, this valve ensures reliable and efficient performance across various applications.
