The Sun Hydraulics DDDCXYN/AP (Material Number: DDDCXYN/AP) is a three-position, 4-way directional cartridge valve designed for high-pressure hydraulic applications. This spring-centered, 6-port directional valve offers versatility through various spool options, ensuring adaptability to different operational requirements. Each port on this valve, including the X and Y pilot ports (port 1 and port 6), can handle up to 5000 psi (350 bar). The capacity of the DDDCXYN/AP to shift the valve depends on the specified spool type, with a general capacity of up to 20 gpm (80 L/min). This model features a hardened spool and sleeve that not only reduce leakage rates but also enhance wear characteristics, contributing to the valve's durability and consistent performance. The incorporation of Sun's floating style construction minimizes internal parts binding, which could otherwise occur due to excessive installation torque or variations in cavity/cartridge machining. Furthermore, it requires a minimum pilot pressure of 150 psi (10.5 bar) to shift the valve effectively. The maximum operating pressure for this model is maintained at 5000 psi (350 bar), with maximum valve leakage specified at 2 in\u00b3/min at 1000 psi (30 cc/min at 70 bar). The pilot volume displacement is relatively low at .05 in\u00b3 (0.82 cc), ensuring precise control during operation. For installation, the valve hex size is noted as 1-1/8 in. (28.6 mm), with an installation torque range between 45 \u2013 50 lbf\u00b7ft (61 \u2013 68 Nm). The seal kit for this cartridge uses Viton material (Part No: 990052006), known for its high performance under varying conditions.
