The Sun Hydraulics DMDATRV612N (DMDATRV612N) is a high-performance solenoid-operated 3-way, 2-position cartridge valve. This direct-acting, balanced spool directional valve is specifically designed for robust industrial applications requiring precise control. With a maximum operating pressure of 5000 psi (350 bar) and a flow capacity of 12 gpm (45 L/min), it serves effectively in various hydraulic systems. This model features a solenoid tube assembly that is fatigue rated for high-pressure service, ensuring durability and reliability even under strenuous conditions. The valve incorporates closed transitions between spool positions B and R, optimizing performance by providing faster and more consistent response times, especially suitable for pilot control applications where capacity is less critical. Notably, the DMDATRV612N operates without requiring a minimum hydraulic pressure, enhancing its versatility across different hydraulic setups. It includes options for manual override controls (D, L, T types), which are primarily intended for temporary actuation with a mechanical life expectancy of around 7,000 cycles. The valve's design uses EPDM seals suitable for phosphate ester fluids but should avoid contact with petroleum-based fluids to prevent seal damage. Additionally, its wet armature design allows the working fluid to surround the armature; however, caution is needed as prolonged coil energization can lead to fluid breakdown in certain conditions. For ease of integration and maintenance, the coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. The construction also minimizes internal parts binding by incorporating Sun\u2019s floating style construction which accounts for installation torque and cavity-cartridge machining variations. This makes the DMDATRV612N an adaptable solution suited to meet rigorous industrial demands while ensuring operational consistency and longevity.
