The Sun Hydraulics DCFBDHN (DCFBDHN) is a robust two-position, detented, 4-way directional cartridge valve designed for high-pressure hydraulic systems. This model features six ports with the supply port designated as port 1. Each port on this valve, including the x and y pilot ports (port 5 and port 6), can handle pressures up to 5000 psi (350 bar). The DCFBDHN offers various spool options that affect its flow capacity, which ranges from 80 to 120 gpm (320 to 480 L/min), making it versatile for different hydraulic applications. The valve is engineered with a hardened spool and sleeve that ensure low leakage rates and superior wear characteristics, essential for maintaining system efficiency and longevity. Additionally, the DCFBDHN incorporates Sun\u2019s floating style construction. This design feature minimizes the risk of internal parts binding which can occur due to excessive installation torque or variations in cavity/cartridge machining. Key technical specifications include a maximum operating pressure of 5000 psi (350 bar), maximum valve leakage at 110 SUS (24 cSt) of 2 in\u00b3/min per 1000 psi (30 cc/min per 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 inches (41.3 mm) and an installation torque between 350 -375 lbf\u00b7ft (474 -508 Nm). The model weighs approximately 3.80 lbs (1.75 kg). This valve is suitable for applications requiring precise control over direction and flow in hydraulic circuits under high pressure, providing reliability through its durable construction and design innovations aimed at enhancing performance and ease of use.
