The Sun Hydraulics DCDADBN (DCDADBN) is a highly versatile three-position, 4-way directional cartridge valve, engineered for complex hydraulic systems requiring reliable directional control. This spring-centered valve features six ports, including X and Y pilot ports (port 5 and port 6), each capable of handling pressures up to 5000 psi (350 bar). Users can select from ten different spool options, allowing customization according to specific application needs. The valve operates within a flow capacity range of 11 to 30 gpm (38 to 120 L/min) and requires a minimum pilot pressure of 150 psi (10.5 bar) to shift the valve effectively. Constructed with a hardened spool and sleeve, the DCDADBN ensures low leakage rates and superior wear characteristics, critical for maintaining system efficiency and longevity. This model 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. The maximum operating pressure for this model is consistent at 5000 psi (350 bar), with maximum valve leakage noted at 2 in\u00b3/min at 1000 psi (30 cc/min at 70 bar). For installation, the valve hex size is specified at 1-1/8 inches (28.6 mm) with an installation torque range of 45 -50 lbf\u00b7ft (61 -68 Nm). The model weighs approximately .80 lb (0.35 kg), making it compact yet robust enough for demanding applications. It uses Viton seals for enhanced performance under varying conditions, ensuring reliability and durability in diverse operational environments.
