The Sun Hydraulics DMDAXRN4E12V (DMDAXRN4E12V) is a solenoid-operated 3-way, 2-position cartridge valve that offers robust performance in hydraulic systems. This direct-acting, balanced spool directional valve is designed to handle a maximum operating pressure of 5000 psi (350 bar) and has a flow capacity of up to 12 gpm (45 L/min). It features a fatigue-rated solenoid tube assembly for high-pressure service and closed transitions between spool positions B and R, enhancing performance by ensuring faster and more consistent response times, particularly suitable for pilot control applications where capacity is less critical. The valve operates without requiring a minimum hydraulic pressure, making it highly effective in various operational scenarios. It includes manual override options with the D or L control having a detent mechanism designed for temporary actuation, supporting around 7,000 cycles mechanically. The valve\u2019s design incorporates EPDM seals suitable for phosphate ester fluids; however, these seals are susceptible to damage when exposed to petroleum-based fluids. A notable feature of the DMDAXRN4E12V is its wet armature design which exposes the armature to working fluid, potentially affecting performance if the coil remains energized over extended periods. This can lead to breakdowns in certain fluids like water-glycol mixtures at high temperatures. For maintenance and compatibility across systems, its coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. Additionally, Sun Hydraulics has engineered this model with their floating style construction to minimize internal part binding caused by excessive installation torque or cavity/cartridge machining variations. This thoughtful design consideration ensures reliable operation and longevity of the valve even under challenging installation conditions.
