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.

TECHNICAL FEATURES

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.
