The Sun Hydraulics DMDATNN712 (DMDATNN712) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for precise hydraulic fluid direction control. This direct-acting, balanced spool directional valve boasts a robust construction that is fatigue rated for 5000 psi (350 bar) service, making it suitable for high-pressure applications. The valve features closed transitions between Spools B and R, which enhances performance by providing faster and more consistent response times especially in pilot control applications where flow capacity is less critical. The DMDATNN712 operates without requiring a minimum hydraulic pressure, thus ensuring reliable functionality across various conditions. For manual override operations, the valve includes detent mechanisms designated by D or L control options, with an expected mechanical life of around 7,000 cycles. It is essential to note that cartridges with EPDM seals are specifically designed for systems using phosphate ester fluids; exposure to petroleum-based fluids can damage these seals. This model incorporates a wet armature design where the working fluid surrounds the armature. This design aspect needs careful consideration as prolonged energization of the coil can lead to higher fluid temperatures which may degrade certain types of hydraulic fluids. Additionally, the interchangeable coils compatible with other Sun Series 1 solenoid products offer flexibility in maintenance and replacement processes. Key specifications include a maximum operating pressure of 5000 psi (350 bar), flow capacity up to 12 gpm (45 L/min), and typical response times around 50 ms. The valve also supports switching frequencies up to 15,000 cycles per hour and features Sun\u2019s floating style construction which minimizes internal part binding due to installation variances. This product's adaptability and durability make it an excellent choice for demanding hydraulic systems requiring precise control and reliable operation under high-pressure conditions.
