The Sun Hydraulics DMDAMAV712N (DMDAMAV712N) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for robust and efficient hydraulic system operations. This direct-acting, balanced spool directional valve is equipped with a solenoid tube assembly that is fatigue rated for 5000 psi (350 bar) service, ensuring reliability under high-pressure conditions. The valve features closed transitions between positions B and R, enhancing performance by providing faster and more consistent response times especially when used as pilot controls where capacity is less critical. Additionally, the DMDAMAV712N requires no minimum hydraulic pressure to operate, making it versatile for various applications. It includes manual override options with a detent mechanism designed for temporary actuation; these manual controls (D, L, and T) have a mechanical life expectancy of around 7,000 cycles. The valve is configured to work with EPDM seals suitable for systems using phosphate ester fluids; however, these seals must avoid exposure to petroleum-based substances to prevent damage. Another notable feature of the DMDAMAV712N is its wet armature design which allows the working fluid to surround the armature. This design consideration is crucial when the coil is energized for extended periods as it can affect fluid integrity over time. For ease of integration and maintenance, its coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. The construction incorporates Sun's floating style to minimize internal parts binding due to excessive installation torque or cavity/cartridge machining variations. With a maximum operating pressure of 5000 psi (350 bar), a typical response time of 50 ms, and a capacity of up to 12 gpm (45 L/min), this valve ensures efficient flow control in demanding applications.
