The Sun Hydraulics DMDAXBV4E12V (DMDAXBV4E12V) is a high-performance 3-way, 2-position cartridge valve designed for robust hydraulic system applications. Featuring a direct-acting, balanced spool design, this valve ensures efficient control with its closed transition spools B and R, enhancing performance by providing faster and more consistent response times when used as pilot controls. The unit operates effectively without minimum hydraulic pressure, thanks to its direct actuation mechanism. Constructed to handle pressures up to 5000 psi (350 bar), the DMDAXBV4E12V is fatigue rated and suitable for demanding environments. It incorporates a wet armature design, where the working fluid surrounds the armature to manage the heat generated by the coil. This design consideration is crucial for applications where the coil remains energized over extended periods, although care must be taken with certain fluids that may degrade under such conditions. The solenoid coils of this model are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction to accommodate different installation requirements. Additionally, the valve features Sun's floating style construction which minimizes internal part binding due to installation torque or machining variations of cavity/cartridge. With a flow capacity of 12 gpm (45 L/min) and rapid response times typical at 50 ms, the DMDAXBV4E12V meets stringent performance criteria for various hydraulic applications. The manual override feature includes a detent mechanism for temporary actuation with a mechanical life expectancy of approximately 7,000 cycles. This model also supports environmental compatibility with EPDM seals designed specifically for phosphate ester fluids; however, exposure to petroleum-based substances should be avoided to prevent seal damage. Overall, Sun Hydraulics' DMDAXBV4E12V offers reliable performance and versatility in hydraulic system management with specific attention to durability and operational efficiency in challenging conditions.
