The Sun Hydraulics DMDAXPV612 (Material Number DMDAXPV612) is a solenoid-operated 3-way, 2-position cartridge valve that excels in performance by being a direct-acting, balanced spool directional valve. This model is specifically designed to handle a maximum operating pressure of 5000 psi (350 bar) and offers a flow capacity of up to 12 gpm (45 L/min). Notably, it features a rapid response time typically around 50 milliseconds and maintains robust performance with a maximum valve leakage at 110 SUS (24 cSt) of approximately 5 in\u00b3/min at 3000 psi (80 cc/min at 210 bar). A key attribute of the DMDAXPV612 is its closed transition between positions B and R, enhancing performance by ensuring faster and more consistent response times, particularly effective when used as pilot controls. It incorporates Sun\u2019s floating style construction which minimizes internal parts binding due to installation torque or cavity/cartridge machining variations. The solenoid tube assembly within this model is fatigue-rated for high-pressure service up to 5000 psi, making it suitable for rigorous applications. The valve's wet armature design indicates that the working fluid surrounds the armature; this arrangement necessitates consideration regarding heat generation if the coil remains energized over extended periods. Additionally, this model supports interchangeable coils with other Sun Series 1 solenoid products and offers flexibility in mounting orientation. For environments involving phosphate ester fluids, cartridges configured with EPDM seals are recommended, while exposure to petroleum-based fluids should be avoided to prevent seal damage. The manual override feature in models equipped with D or L control provides temporary actuation with a mechanical life expectancy of about 7,000 cycles. Overall, the Sun Hydraulics DMDAXPV612 is engineered for durability and precise control in hydraulic systems requiring reliable directional control and fast actuation under high-pressure conditions.
