The Sun Hydraulics DCFADZN (DCFADZN) is a versatile and robust three-position, 4-way directional cartridge valve. This spring-centered, 6-port directional valve offers exceptional operational flexibility with a choice of 10 different spool options to cater to various hydraulic flow requirements. The design ensures that all ports, including the x and y pilot ports (port 5 and port 6), can withstand pressures up to 5000 psi (350 bar). The valve's capacity varies depending on the spool type selected, ranging from 50 to 200 gpm (200 to 760 L/min). Engineered for durability and performance, the DCFADZN features a hardened spool and sleeve that minimize leakage and provide excellent wear characteristics. It incorporates Sun's floating style construction which helps in minimizing internal parts binding\u2014a common issue resulting from excessive installation torque or cavity/cartridge machining variations. This valve is designed for efficient operation with a minimum pilot pressure requirement of 125 psi (9 bar) needed to shift the valve. Additional technical specifications include a maximum operating pressure of 5000 psi (350 bar), maximum valve leakage at 110 SUS (24 cSt) being limited to 2 in\u00b3/min at 1000 psi (30 cc/min at 70 bar), and pilot volume displacement of .42 in\u00b3 (6.9 cc). The hex size for the valve is set at 1-5/8 in. (41.3 mm) with an installation torque requirement between 350 -375 lbf\u00b7ft (474 -508 Nm). The model weighs approximately 3.80 lb (1.75 kg). Sun Hydraulics has also provided an optional Viton seal kit for this model under part number:990064006, ensuring compatibility and maintenance ease across various system configurations.
