The Sun Hydraulics FQEAXBN (FQEAXBN) 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 allows fluid to flow to and from the actuator, but it closes instantly if the flow from the actuator exceeds a pre-set threshold. Due to its rapid response, it is highly sensitive to any transient flow above its setting. Customers must specify a flow rating upon ordering, and factory-set flow ratings are within 10% of the requested setting. The valve 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. Constructed as a spool type valve, some leakage and potential actuator drift may occur. It incorporates Sun's floating style construction, minimizing internal part binding due to excessive installation torque or machining variations. The FQEAXBN fits into cavity T5A, belongs to Series 2, and has a capacity of 15 gpm (60 L/min). It can withstand a maximum operating pressure of 5000 psi (350 bar) with maximum valve leakage at 3 in\u00b3/min (50 cc/min) at 1000 psi (70 bar). The valve hex size measures 1-1/8 inches (28.6 mm), requiring an installation torque between 45-50 lbf ft (61-68 Nm), with an overall weight of .40 lb (.20 kg). For use in corrosive environments, corrosion-resistant options are available under different model codes. Seal kits are available in Viton: part number 990203006 for maintenance purposes.

Flow fuse cartridges are used to maintain the position of a hydraulic actuator in the event of a hose or line break. The valve allows flow to and from the actuator but closes instantly if flow from the actuator exceeds the setting of the valve. NOTE: Because the valve responds so rapidly, it is sensitive to any transient flow above the valve setting.
- Customer must specify a flow rating. Factory set flow ratings are within +/- 10% of the requested setting.
- Valve closes when flow from port 1 to port 2 exceeds the setting of the valve. Valve resets when pressures at port 1 and port 2 are equal.
- Flow setting should be at least 25% above maximum normal system flow. Customer must specify flow when ordering valve.
- These are spool type valves, therefore there is leakage. Some actuator drift may occur.
- Corrosion resistant cartridge valves are intended for use in corrosive environments and are identified by the model code suffix /AP or /LH (see CONFIGURATION section). For further details, please see the Materials of Construction page under TECHNICAL RESOURCES.
- Incorporates the Sun floating style construction to minimize the possibility of internal parts binding due to excessive installation torque and/or cavity/cartridge machining variations.
