The Sun Hydraulics DMDATNN712N (DMDATNN712N) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve. This direct-acting, balanced spool directional valve is designed for robust operation and precise control. It features a fatigue-rated solenoid tube assembly suitable for up to 5000 psi (350 bar) service, ensuring durability under high-pressure applications. The spools B and R are closed during the transition between positions, optimizing performance by providing faster and more consistent response times, particularly beneficial when used as pilot controls. This valve operates without the need for minimum hydraulic pressure, facilitating its use in a variety of fluid power systems. It incorporates manual override options with detent mechanisms designed for temporary actuation and has an expected mechanical life of approximately 7,000 cycles. Special attention is given to its compatibility with fluids; models with EPDM seals are specifically intended for systems using phosphate ester fluids while avoiding exposure to petroleum-based substances which could damage the seals. The design includes a wet armature setup where the working fluid surrounds the armature; this aspect needs consideration regarding heat dissipation if the coil remains energized over extended periods. Additionally, it features interchangeable coils with other Sun Series 1 solenoid products and supports a floating style construction that minimizes internal parts binding due to installation torque or machining variations. Key specifications include a flow capacity of 12 gpm (45 L/min), maximum operating pressure of 5000 psi (350 bar), typical response time of 50 ms, and a switching frequency capable of handling up to 15,000 cycles per hour. The compact design weighs only 0.60 lb (0.30 kg), making it suitable for various installation environments without adding significant weight or bulk.
