Dwyer Instruments V8 Flotect flow switch

Click2Contact

The V8 Flotect flow switch has a leakproof body and vane constructed of tough durable polyphenylene sulfide which has excellent chemical resistance.

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 5 A at 120/250 VAC to start or stop a motor, pump or engine; or to operate a damper or valve; shut down a burner; or actuate an alarm or signal.

The full-size trimmable vane is provided with moulded-in graduations allowing for installation in a 1″ through 6″ pipe. Operating pressures are up to 150 psig (10 bar) and temperatures to 100°C. The V8 flow switch can be used in various chemical processes, industrial systems and similar applications where process conditions are compatible with polyphenylene sulfide, ceramic 8 and 316 stainless steel.

The V8 switch is useful for applications in chemical processing, liquid transfer systems, water treatment, air conditioning, refrigeration, heating systems, cooling lines, machinery, food processing and machine tools.
