The Sun Hydraulics DDDCXDN (DDDCXDN) is a versatile, three-position, 4-way directional cartridge valve designed for high-pressure hydraulic systems. This model features a spring-centered mechanism and six ports, including supply port 3 and pilot ports 1 and 6, each capable of handling up to 5000 psi (350 bar). The valve's operational capacity varies depending on the spool type selected, supporting up to 20 gpm (80 L/min). Constructed with a hardened spool and sleeve, the DDDCXDN ensures low leakage rates and superior wear characteristics, crucial for maintaining efficiency and prolonging the valve\u2019s lifespan in demanding environments. It also incorporates Sun\u2019s floating style construction which minimizes internal parts binding\u2014a common issue in valves due to excessive installation torque or variations in cavity/cartridge machining. Key specifications include a minimum pilot pressure requirement of 150 psi (10.5 bar) for valve shifting, a maximum operating pressure of 5000 psi (350 bar), and maximum valve leakage at 110 SUS (24 cSt) being 2 in\u00b3/min at 1000 psi (30 cc/min at 70 bar). The valve also features a pilot volume displacement of .05 in\u00b3 (0.82 cc), with an installation torque requirement between 45-50 lbf\u00b7ft (61-68 Nm). This model is particularly suitable for applications requiring reliable performance under high pressures and variable flow conditions. Its robust design ensures it can be used effectively across various hydraulic applications without concerns over performance degradation due to wear or external pressures on the system components.
