Dwyer Instruments V8 Flow Switch

The Dwyer Instruments V8 Flotect Vane Operated Flow Switch is a heavy-duty solution for protecting HVACR and industrial equipment from damage caused by flow loss. Engineered with a leak proof body and vane constructed from polyphenylene sulfide (PPS), this unit offers superior chemical resistance in demanding environments. This field adjustable flow switch features a trimmable vane with molded-in graduations, allowing for precise setup in 1" to 6" pipe sizes. The SPDT snap switch provides reliable liquid flow monitoring and signaling for motors, pumps, or alarms, with an electrical rating of 5A at 125/250 VAC. Designed for horizontal pipe runs, the V8 utilizes a magnetic coupling to actuate the switch, eliminating the need for bellows or seals that typically fatigue over time. With a 1" NPT male process connection and a maximum pressure rating of 150 psig at temperatures up to 212°F, this vane operated switch is a versatile choice for water treatment, cooling lines, and liquid transfer systems.

Key Benefits for Contractors
  • Universal Compatibility: Trimmable vane design allows for standard stocking across multiple pipe diameters from 1" to 6".
  • Enhanced Durability: PPS construction and a 316 stainless steel pin ensure compatibility with clean, non-corrosive liquids and various chemical processes.
  • Leak-Free Design: High-pressure 150 psi rating with a solid metal-to-plastic interface prevents process fluid from entering the electrical housing.
  • Simplified Installation: Standard 1" NPT process connection and 18 AWG lead wires facilitate fast integration into existing control loops.
  • Magnetic Actuation: Uses a free-swinging vane and magnet to actuate the internal switch, removing common point-of-failure components like springs or bellows.
Common Questions & Installation Tips Can this switch be used in vertical piping? No, the Dwyer V8 is designed specifically for horizontal pipe runs. Installing it in a vertical down-flow configuration will cause inaccurate actuation and potential switch failure. How do I adjust the set point for different pipe sizes? The vane includes molded-in graduations. Technicians must trim the vane at the mark corresponding to the pipe size in use. For standard bronze or iron fittings, it is recommended to trim 0.125" above the mark to ensure proper clearance. What are the wiring color codes for the SPDT switch? The 18" lead wires follow standard industry coloring: Black is Common, Red is Normally Open (NO), and Blue is Normally Closed (NC).
