The Sun Hydraulics DMDATNV612 (DMDATNV612) is a solenoid-operated 3-way, 2-position cartridge valve that features a direct-acting, balanced spool for precise control in hydraulic systems. This model is designed to be fatigue rated for high-pressure applications up to 5000 psi or 350 bar, making it suitable for rigorous industrial environments. The valve offers a closed transition between its two positions (spools B and R), enhancing performance by providing faster and more consistent response times, especially beneficial in pilot control applications where capacity is less critical. The DMDATNV612 operates without the need for minimum hydraulic pressure, facilitating its use across a broad range of operating conditions. It includes options for manual overrides with detent mechanisms (models with D or L control), intended for temporary actuation with a mechanical life expectancy of approximately 7,000 cycles. For compatibility with different fluid types, cartridges configured with EPDM seals are specifically designed for systems using phosphate ester fluids; however, these seals must avoid contact with petroleum-based fluids to prevent damage. Notably, the valve employs a wet armature design where the working fluid surrounds the armature. This setup needs consideration if the coil remains energized for extended periods due to potential breakdowns in certain fluids like water-glycol mixtures at high temperatures. The DMDATNV612 also features interchangeable coils compatible with other Sun Series 1 solenoid products and a floating style construction that minimizes internal part binding caused by installation torque or cavity/cartridge machining variations. This model supports up to 12 gpm/45 L/min capacity and has typical response times of around 50 ms. Its robust design includes features such as maximum valve leakage at 110 SUS (24 cSt) being limited to 5 in\u00b3/min at 3000 psi (80 cc/min at 210 bar), and it can handle switching frequencies up to 15000 cycles/hr. The manual override requires minimal force, further enhancing usability and maintenance simplicity in demanding applications.
