Flotect Flow Switches
Series V8 Flotect Vane Operated Flow Switch
Field Adjustable — 1 to 6 Inch Pipe — Leak Proof Body
Model V8
Model V8-WP2
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 @ 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, protecting unattended equipment from damage or loss of production.
The V8 Flotect® Flow Switch has a 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 1” through 6” pipe. The V8 is UL recognized as an industrial motor controller per UL standard 508, suitable for mounting in a protected environment.
