The Sun Hydraulics FQGAXBV (FQGAXBV) 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 flow to and from the actuator but will close instantly if the flow exceeds its set threshold, making it essential for preventing uncontrolled actuator movement. With a capacity of 25 gpm (95 L/min) and a maximum operating pressure of 5000 psi (350 bar), this spool-type valve provides reliable performance in demanding environments. It features Sun's floating style construction, minimizing internal binding due to excessive installation torque or machining variations. The FQGAXBV requires customers to specify a flow rating, with factory-set ratings within 10% of the requested setting. It is important that the flow setting be at least 25% above normal system flow to prevent false tripping caused by transient flows exceeding the valve's setting. The valve resets when pressures at ports 1 and 2 are equalized, though some leakage and actuator drift may occur due to its spool-type design. Installation specifics include a T-16A cavity, a valve hex size of 1-1/4 inches (31.8 mm), and an installation torque between 150 - 160 lbf ft (203 - 217 Nm). The model weighs approximately .70 lbs (.30 kg) and uses Viton seals with seal kit part number 990016006 available for maintenance needs. This product is not suitable for preventing oil loss or fire protection but serves as an effective solution against uncontrolled actuator movement in hydraulic systems with potential hose failure risks.

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.
