The Sun Hydraulics DCDADWN (DCDADWN) is a three-position, 4-way directional cartridge valve designed for high-pressure hydraulic systems. This spring-centered, 6-port directional valve offers a variety of 10 different spool options to cater to specific system requirements. With a maximum operating pressure of 5000 psi (350 bar), the valve is suitable for demanding applications where precise fluid control is necessary. Each port on the DCDADWN, including the x and y pilot ports (port 5 and port 6), can handle pressures up to 5000 psi. The capacity of this pilot-to-shift valve varies depending on the spool type chosen and ranges from 11 to 30 gpm (38 to 120 L/min). It requires a minimum pilot pressure of 150 psi (10.5 bar) to shift the valve, ensuring reliable operation under varied conditions. The DCDADWN features hardened spool and sleeve components that not only offer excellent wear characteristics but also ensure consistent and low leakage rates. The design incorporates Sun's floating style construction which reduces the risk of internal parts binding due to excessive installation torque or cavity/cartridge machining variations. This feature enhances the overall durability and reliability of the valve. Technical specifications include a maximum valve leakage at 110 SUS (24 cSt) rated at 2 in\u00b3/min at 1000 psi (30 cc/min at 70 bar), and a pilot volume displacement of .06 in\u00b3 (0.98 cc). For installation, it has a hex size requirement of 1-1/8 in (28.6 mm) and an installation torque between 45 -50 lbf\u00b7ft (61 -68 Nm). The model weighs approximately .80 lb (0.35 kg), making it compact yet robust for industrial hydraulic applications.
