    Series V7 Flotect® Vane Operated Flow Switch

    Magnetic Linkage

    The SERIES V7 Flotect® Flow Switch is an inexpensive range switch for use with compatible liquids to start or stop electronic operated equipment when flow or no-flow conditions occur. Design is standard weatherproof, meeting NEMA 4X.

    Product Applications

    • Proof of boiler flow
    • Shuts down burner when air flow through heating coil fails
    • Protects pumps, motors and other equipment against low or no flow
    • Stops liquid cooled engines, machines and processing when coolant flow is interrupted

    • Magnetically actuated switching design gives superior performance
    • Features a free-swinging vane which attracts a magnet within the solid metal switch body, actuating a snap switch by means of a simple lever arm with no bellows, springs, or seals to fail
    • Lower body is machined solid metal bar stock assuring no leak points, no matter how long the unit is in service
    • Robust vane design is rigid and field trimmable for set point adjustment
