The Sun Hydraulics DMDAXPN914N (DMDAXPN914N) is a high-performance solenoid-operated 3-way, 2-position cartridge valve. This direct-acting, balanced spool directional valve is designed for robust operation in hydraulic systems. It is fatigue rated at 5000 psi or 350 bar, making it suitable for high-pressure applications. The valve features closed spools B and R during the transition between positions to enhance performance by providing faster and more consistent response times, especially useful in pilot control applications where capacity is less of a concern. The DMDAXPN914N requires no minimum hydraulic pressure to operate and includes manual override options with a detent mechanism designed for temporary actuation, supporting up to approximately 7,000 cycles. The valve uses EPDM seals suitable for phosphate ester fluids; however, these seals are susceptible to damage if exposed to petroleum-based fluids. Its wet armature design allows the working fluid to surround the armature which could be a consideration when the coil is energized for extended periods as some fluids may degrade under heat. This model also benefits from interchangeable coils with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. It incorporates Sun's floating style construction which minimizes internal parts binding due to installation torque or variations in cavity/cartridge machining. The valve operates with a typical response time of 50 ms and has a maximum operating capacity of 12 gpm (45 L/min). Other technical specifications include a switching frequency up to 15000 cycles/hr, manual override force requirement of 5 lbs at 1000 psi, and minimal leakage at high pressures ensuring efficient operation across various hydraulic applications.
