Series G9 Globe Flow Switch

Adjustable Set Point, Water or Oil Service, 90° Flow Path

The Series G9 Globe Flow Switch provides accurate flow detection in water and oil with ±1% repeatability. A shuttle bypass vane inside the housing is controlled externally using an ordinary flat blade screwdriver, allowing flow settings to be changed without disassembly. Each switch is constructed of noncorrosive materials and resists shock and vibration. The Series G9 is suitable for triggering alarms on interlocking shutdown circuitry when flow rate is incorrect and for protecting bearings, gears, and cooling systems.
