The Sun Hydraulics DMDAMRV4E12V (Material Number: DMDAMRV4E12V) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve. This direct-acting, balanced spool directional valve is designed for use in hydraulic systems requiring reliable control of fluid direction. It features a fatigue-rated solenoid tube assembly suitable for pressures up to 5000 psi (350 bar), ensuring durability and longevity under high-pressure conditions. The spools B and R remain closed during the transition between positions, optimizing performance by providing faster and more consistent response times, particularly beneficial when used as pilot controls. The valve operates without requiring a minimum hydraulic pressure, enhancing its versatility across various applications. It includes a manual override with a detent mechanism designed for temporary actuation, with an expected mechanical life of approximately 7,000 cycles. The DMDAMRV4E12V is equipped with EPDM seals suitable for phosphate ester fluids but must avoid exposure to petroleum-based substances to prevent seal damage. Engineered with a wet armature design, the valve's armature is immersed in the working fluid which helps manage heat dissipation from the coil\u2014important when the coil remains energized for extended periods. This design consideration ensures that the valve remains functional even when subjected to thermal stresses that could degrade certain types of hydraulic fluids. Additionally, this model supports interchangeable coils with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. Its design incorporates Sun's floating style construction that minimizes internal parts binding caused by excessive installation torque or variations in cavity/cartridge machining. With specifications like a maximum operating pressure of 5000 psi (350 bar), flow capacity up to 12 gpm (45 L/min), and typical response time as quick as 50 ms, this valve is tailored for applications demanding precise control and robust performance.
