The Sun Hydraulics DMDAXPN714 (DMDAXPN714) is a high-performance solenoid-operated 3-way, 2-position cartridge valve. It features a direct-acting, balanced spool directional design that effectively manages hydraulic flow with precision. The valve operates with no minimum hydraulic pressure requirement, enabling reliable performance across a variety of applications. This model boasts a robust fatigue rating for 5000 psi (350 bar) service, making it suitable for demanding environments. The DMDAXPN714 is designed with closed transitions between Spools B and R, enhancing performance by ensuring faster and more consistent response times in pilot control applications where capacity is less critical. The manual override in models equipped with the D or L control uses a detent mechanism intended for temporary actuation, supporting a mechanical life expectancy of about 7,000 cycles. This valve utilizes EPDM seals configured specifically for systems using phosphate ester fluids; however, exposure to petroleum-based fluids should be avoided as it can damage the seals. Additionally, the wet armature design implies that the working fluid surrounds the armature which could lead to breakdowns if exposed to high temperatures for extended periods. For installation and maintenance ease, its coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. The construction incorporates Sun's floating style to minimize internal parts binding due to excessive installation torque or cavity/cartridge machining variations. Key specifications include a maximum operating pressure of 5000 psi (350 bar), typical response time of 50 ms, and a flow capacity up to 12 gpm (45 L/min). This model\u2019s switching frequency can reach up to 15,000 cycles/hr, making it an efficient choice for systems requiring frequent operation cycles.
