The Sun Hydraulics FQEAXAN (FQEAXAN) is a flow fuse cartridge designed to maintain the position of a hydraulic actuator in the event of a hose or line break. This valve permits fluid flow to and from the actuator but will close instantly if the flow from the actuator exceeds the pre-set limit. It is crucial for customers to specify a flow rating, as factory settings are within 10% of this request. The valve automatically closes when the flow from port 1 to port 2 surpasses its setting and resets when pressures at both ports equalize. The recommended flow setting should be at least 25% above the maximum normal system flow to prevent false tripping, which can occur due to transient flows exceeding valve settings. The FQEAXAN is constructed with corrosion-resistant materials, identified by specific model code suffixes for use in corrosive environments. It employs Sun's floating style construction, minimizing internal binding due to excessive torque or machining variations. This spool-type valve may experience some leakage, resulting in minor actuator drift. It fits into a T5A cavity and belongs to Series 2 with a capacity of 15 gpm (60 L/min) and can withstand a maximum operating pressure of 5000 psi (350 bar). The maximum valve leakage at 110 SUS (24 cSt) is rated at 3 in\u00b3/min (1000 psi) or approximately 50 cc/min (70 bar). The valve's hex size measures 1-1/8 inches (28.6 mm), and it requires an installation torque between 45-50 lbf\u00b7ft (61-68 Nm). The model weighs approximately .40 lb (.20 kg), and Viton seal kits are available under part number 990203006 for maintenance needs.
