The Sun Hydraulics DDHCXHN (DDHCXHN) is a three-position, 4-way directional cartridge valve that is spring-centered and features a 6-port configuration. This model is designed to handle a maximum operating pressure of 5000 psi (350 bar), with all ports, including the x and y pilot ports (port 5 and port 6), accepting this pressure level. The valve's capacity to shift fluid depends on the spool type specified, with a flow capacity up to 80 gpm (320 L/min). The DDHCXHN requires a minimum pilot pressure of 200 psi (14 bar) to shift the valve, ensuring reliable operation under various conditions. This model incorporates Sun's floating style construction which minimizes the risk of internal parts binding due to excessive installation torque or variations in cavity/cartridge machining. The hardened spool and sleeve enhance durability by providing consistent low spool leakage rates and excellent wear characteristics. The maximum valve leakage at an operating condition of 110 SUS (24 cSt) is limited to 5 in\u00b3/min per 1000 psi (80 cc/min per 70 bar), demonstrating its efficiency in maintaining system integrity. The DDHCXHN has specific installation requirements with a valve hex size of 1-5/8 inches (41.3 mm) and an installation torque range between 350 -375 lbf\u00b7ft (474 -508 Nm). Weighing at approximately 5.9 lbs (2.7 kg), this model also supports Viton seal kits for enhanced chemical resistance and durability under various operational environments. This directional cartridge is an essential component for systems requiring precise control over fluid direction and pressure within hydraulic circuits.
