The Sun Hydraulics DDDCXYN (DDDCXYN) is a high-performance, three-position, 4-way directional cartridge valve. This spring-centered, 6-port directional valve offers robust control for hydraulic systems, featuring a range of spool options that allow for customization based on specific operational requirements. The valve's supply port is designated as port 3, and it has the capacity to handle up to 5000 psi (350 bar) across all ports including the x and y pilot ports (port 1 and port 6). Notably engineered for low leakage and high durability, the DDDCXYN incorporates a hardened spool and sleeve which ensure minimal spool leakage rates while providing excellent wear characteristics. This model benefits from Sun Hydraulics' floating style construction which reduces the risk of internal parts binding due to excessive installation torque or variations in cavity/cartridge machining. With a flow capacity of up to 20 gpm (80 L/min), the DDDCXYN requires a minimum pilot pressure of 150 psi (10.5 bar) to shift the valve effectively. The maximum operating pressure capability stands at 5000 psi (350 bar), with maximum valve leakage noted at 2 in\u00b3/min at 1000 psi (30 cc/min at 70 bar). The pilot volume displacement is recorded at .05 in\u00b3 (.82 cc), ensuring efficient operation even under stringent conditions. Installation specifications include a valve hex size of 1-1/8 inches (28.6 mm) and an installation torque ranging between 45-50 lbf\u00b7ft (61-68 Nm). The seal kit for this cartridge uses Viton material, part number: 990052006, ensuring reliable sealing and performance continuity in varied hydraulic applications.
