The Sun Hydraulics FQIAXBV (FQIAXBV) is a flow fuse cartridge designed to ensure the stability of hydraulic actuators in the event of a hose or line break. This valve allows fluid to flow to and from the actuator but instantly closes if the flow exceeds the preset limit, preventing uncontrolled movement. It's crucial for users to specify a flow rating upon ordering, as factory-set ratings are within 10% of the requested setting. The valve activates when flow from port 1 to port 2 surpasses its limit and resets when pressures at both ports equalize. For optimal performance, the flow setting should be at least 25% above normal system flow to avoid false tripping due to transient flows. The FQIAXBV incorporates Sun's floating style construction, which minimizes internal part binding caused by excessive installation torque or cavity machining variations. It features a T18A cavity with a series 4 capacity, allowing up to 50 gpm (200 L/min) and can withstand a maximum operating pressure of 5000 psi (350 bar). However, as it is a spool-type valve, some leakage may occur, potentially causing actuator drift. The maximum valve leakage at 110 SUS (24 cSt) is rated at 5 in/min (1000 psi) or 80 cc/min (70 bar). The valve has a hex size of 1-5/8 inches (41.3 mm) and requires an installation torque between 350 and 375 lbf ft (475-508 Nm). Weighing in at approximately 2.90 lb (1.30 kg), it comes with an optional Viton seal kit for enhanced durability. This product is not intended for oil loss prevention or fire protection but serves primarily as a safety mechanism against actuator movement due to hose failure. Proper selection and tuning are essential for effective application in hydraulic systems where precise control is necessary.

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.
- 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.
