Speciality

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 +/- 15% 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.
