The Sun Hydraulics DMDATNN514 (DMDATNN514) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for precise hydraulic control. This direct-acting, balanced spool directional valve is distinguished by its robust construction, featuring a solenoid tube assembly that is fatigue rated for 5000 psi (350 bar) service. The valve ensures closed transitions between Spools B and R, optimizing performance by prioritizing faster and more consistent response times over capacity, making it ideal for use as pilot controls where capacity is less critical. The DMDATNN514 operates without the need for minimum hydraulic pressure, enhancing its versatility in various applications. It includes options for manual override through D, L, or T control types, with a mechanical life expectancy of approximately 7,000 cycles. The manual override feature is designed primarily for temporary actuation. Special attention is required when selecting seals; cartridges configured with EPDM seals are specifically intended for systems using phosphate ester fluids and must avoid exposure to petroleum-based substances to prevent seal damage. This model also utilizes a wet armature design which allows the working fluid to surround the armature\u2014important to consider as prolonged coil energization can lead to fluid degradation at high temperatures. The design incorporates interchangeable coils compatible with other Sun Series 1 solenoid products and features Sun\u2019s floating style construction which minimizes internal binding due to installation torque or cavity/cartridge 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 maximum valve leakage at 110 SUS (24 cSt) rated at 5 in\u00b3/min at 3000 psi (80 cc/min at 210 bar). The switching frequency stands at up to 15,000 cycles per hour. Installation requires a torque between 30 - 35 lbf\u00b7ft (41 - 47 Nm), and the model weighs approximately 0.60 lb (0.30 kg).
