The Sun Hydraulics DCFBXHN (DCFBXHN) is a robust two-position, detented, 4-way directional cartridge valve designed to operate under high pressure conditions up to 5000 psi (350 bar). This model features six ports, including the X and Y pilot ports (port 5 and port 6), each capable of handling the maximum operating pressure. The DCFBXHN is available with up to three different spool options, influencing its capacity which ranges between 80-120 gpm (320-480 L/min). Key attributes of the DCFBXHN include a hardened spool and sleeve that ensure low leakage rates and superior wear characteristics, crucial for maintaining efficiency and prolonging service life in demanding applications. The valve also incorporates Sun\u2019s floating style construction which helps minimize internal parts binding\u2014a common issue arising from excessive installation torque or cavity/cartridge machining variations. Technical specifications further detail a maximum valve leakage at 110 SUS (24 cSt) of approximately 2 in\u00b3/min at 1000 psi (30 cc/min at 70 bar), and a pilot volume displacement of .84 in\u00b3 (14 cc). For installation, the valve requires a hex size of 1 5/8 in. (41.3 mm) and an installation torque between 350 -375 lbf ft (474 -508 Nm). The model weighs around 3.80 lbs (1.75 kg). This valve is particularly suited for applications requiring reliable performance under high pressure conditions, offering both durability and precision in control. Its design considerations make it an excellent choice for systems where space and reliability are critical factors.
