- V8 Flotect flow switch protects equipment: operation is simple and dependable
- In most applications, the switch is normally off while there is sufficient flow of liquid or air When flow stops, the vane spring moves the vane, actuating a single pole double throw switch rated 5A at 120/250V AC to start or stop motor, pump, engine
- Operate a damper or valve; shut down a burner or actuate an alarm or signal, protecting unattended equipment from damage or loss of production
- With leak proof body and vane constructed of tough durable polyphenylene sulfide which has excellent chemical resistance
- The full size trimmable vane is provided with molded-in graduations allowing for installation in a 1-inch through 6-inch pipe
