The Sun Hydraulics FQEAXAV (FQEAXAV) is a highly efficient flow fuse cartridge designed to maintain the position of a hydraulic actuator in case of a hose or line break. This device allows for normal flow to and from the actuator but will close instantly if the flow exceeds the valve's preset limit, ensuring safety and preventing uncontrolled actuator movement. Customers must specify their desired flow rating, as factory settings are within 10% of this requested value. The valve automatically resets when pressures at its ports equalize, and it is recommended that the flow setting be at least 25% above the maximum normal system flow to prevent false tripping. This spool-type valve may experience some leakage, leading to potential actuator drift. The FQEAXAV model features corrosion-resistant construction suitable for harsh environments, leveraging Sun's floating style design to minimize internal binding due to excessive torque or machining variations. It fits into T5A cavities and belongs to Series 2 with a capacity of 15 gpm (60 L/min) and can operate under maximum pressures up to 5000 psi (350 bar). The valve exhibits minimal leakage at high viscosity levels, with installation requiring a torque between 45\u201350 lbf ft (61\u201368 Nm). Weighing just .40 lb (.20 kg), it offers ease of handling and installation. This model is particularly useful in applications where preventing uncontrolled movement due to hydraulic failures is crucial. However, it should not be used for oil loss prevention or fire protection purposes. Proper setting selection is critical; it should be set well above typical system flows\u2014often around 50% higher\u2014to ensure optimal performance without false tripping during transient flows.
