The Sun Hydraulics DCFADXN (DCFADXN) is a versatile hydraulic valve designed for high-pressure applications. This three-position, 4-way directional cartridge valve is spring-centered and features a six-port configuration that can be tailored with one of ten different spool options, depending on specific application requirements. Each port, including the x and y pilot ports (port 5 and port 6), can handle up to 5000 psi or 350 bar. The DCFADXN model offers a flow capacity ranging from 50 to 200 gpm (200 to 760 L/min), making it suitable for a broad range of hydraulic systems. Key specifications include a minimum pilot pressure requirement of 125 psi or 9 bar for valve shifting, and maximum operating pressure also stands at 5000 psi or 350 bar. The valve exhibits minimal leakage at high pressures, specified at no more than 2 in\u00b3/min per 1000 psi or about 30 cc/min at around 70 bar. It also features pilot volume displacement of approximately .42 in\u00b3 (6.9 cc). Constructed with a hardened spool and sleeve, the DCFADXN ensures low spool leakage rates and excellent wear characteristics over time. Its design incorporates Sun's floating style construction which minimizes internal parts binding\u2014a common issue caused by excessive installation torque or variations in cavity/cartridge machining. 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 about 3.80 lb (1.75 kg), ensuring robust performance without excessive bulk. Additionally, it uses Viton seals for enhanced durability under varying operational conditions.
