The Sun Hydraulics DMDATNV712N (DMDATNV712N) is a solenoid-operated 3-way, 2-position cartridge that functions as a direct-acting, balanced spool directional valve. It features a solenoid tube assembly that is fatigue rated for 5000 psi (350 bar) service, ensuring durability and reliability under high-pressure conditions. This model is designed with closed transitions between Spools B and R, optimizing performance by providing faster and more consistent response times, particularly suitable for applications where capacity is not a critical factor such as pilot controls. The DMDATNV712N operates without requiring a minimum hydraulic pressure, adding to its versatility in various system configurations. It includes options for manual override through the D or L control types, where the detent mechanism is specifically intended for temporary actuation with a mechanical life expectancy of approximately 7,000 cycles. This valve uses EPDM seals when configured for systems utilizing phosphate ester fluids; however, these seals must avoid exposure to petroleum-based fluids to prevent damage. In terms of design, the valve utilizes a wet armature setup where the working fluid surrounds the armature. This aspect needs consideration as prolonged energization of the coil can lead to fluid degradation in certain types like water-glycol mixtures. The interchangeable coils compatible with other Sun Series 1 solenoid products offer flexibility in maintenance and replacement processes. Additional specifications include a maximum operating pressure of 5000 psi (350 bar), flow capacity up to 12 gpm (45 L/min), typical response time of 50 ms, and maximum leakage at 5 in\u00b3/min at 3000 psi. Its robust construction incorporates Sun's floating style construction to reduce risks associated with internal parts binding due to installation issues or cavity/cartridge machining variations.
