NOTE: DATA MAY VARY BY CONFIGURATION. SEE CONFIGURATION SECTION.
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.
