The Sun Hydraulics DMDAMNN514 (DMDAMNN514) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve. This direct-acting, balanced spool directional valve is notable for its robust design which includes a fatigue-rated solenoid tube assembly capable of handling pressures up to 5000 psi (350 bar). It features closed transitions between spool positions B and R, enhancing performance by providing faster and more consistent response times especially suitable for pilot control applications where capacity is less critical. This valve operates without the need for minimum hydraulic pressure, making it versatile across various applications. It is equipped with either D or L control options; the manual override in these models includes a detent mechanism designed for temporary actuation with a mechanical life expectancy of around 7,000 cycles. The EPDM seal configuration is specifically designed for use with phosphate ester fluids, avoiding damage that could be caused by exposure to petroleum-based fluids. Additionally, the DMDAMNN514 utilizes a wet armature design to surround the armature with working fluid, which helps manage heat during prolonged energization but requires consideration of fluid compatibility due to potential breakdowns forming varnishes that could affect performance. The interchangeable coils compatible with other Sun Series 1 solenoid products add flexibility in maintenance and setup. Other technical specifications include a flow capacity of 12 gpm (45 L/min), typical response time of 50 ms, and maximum operating pressure of 5000 psi (350 bar). Leakage specifications are tightly controlled at only 5 in\u00b3/min at 3000 psi. The valve also supports switching frequencies up to 15,000 cycles per hour. For installation and manual operation, it requires an override force of about 5 lbs at 1000 psi and has an override stroke length of .10 inches. The model's weight stands at approximately .60 lb (0.30 kg), ensuring it is lightweight yet durable for industrial applications.
