The Sun Hydraulics DMDAXNN514 (DMDAXNN514) is a solenoid-operated 3-way, 2-position cartridge valve that excels in high-performance applications requiring precise control and reliability. This direct-acting, balanced spool directional valve operates without minimum hydraulic pressure, enhancing its versatility across various hydraulic systems. It features a robust design with a solenoid tube assembly that is fatigue rated for up to 5000 psi (350 bar), ensuring durability and resistance to high-pressure environments. The DMDAXNN514 valve is particularly suitable for pilot control applications due to its closed transitions between spool positions B and R, which allow for faster and more consistent response times without the need for large flow capacities. Additionally, the valve is equipped with EPDM seals intended for use with phosphate ester fluids, although these seals must be protected from exposure to petroleum-based substances to avoid damage. This model incorporates Sun\u2019s floating style construction which minimizes internal parts binding that could result from excessive installation torque or variations in cavity/cartridge machining. The manual override feature in models with D or L control is designed for temporary actuation and has a mechanical life expectancy of about 7,000 cycles. Furthermore, 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 of up to 12 gpm (45 L/min), and a swift typical response time of approximately 50 ms. The valve also supports a high switching frequency of up to 15,000 cycles per hour, making it ideal for systems requiring frequent operation adjustments. With its compact design weighing just 0.60 lb (0.30 kg) and manual override capabilities requiring minimal force, the DMDAXNN514 provides an efficient solution for advanced hydraulic system controls where reliability and performance are critical.
