Dwyer Flow Switch
Model no. V4-SS-2-U-AT
Vane-Operated Flow Switch: Field Adjustable – Dependable Protection Against Flow Variation or Stopping in Pipelines for Fluids, Gases and Flowing Solids.
Features
- Leak proof body machined from bar stock
- Weatherproof, designed to meet NEMA 4
- Explosion-proof
- Installs directly and easily into pipeline with a threaded branch connection, tee, or flange
- Can be used in pipes 1-1/2″ and up
- Electrical assembly can be easily replaced without removing the unit from installation so that the process does not have to be shut down
- High pressure rating of 1000 psig (69 bar) with the brass body and 2000 psig (138 bar) with the 316 SS body
- Unique magnetically actuated switching design gives superior performance
- There are no bellows, springs, or seals to fail
- Instead, a free-swinging vane attracts a magnet within the solid metal switch body, actuating a snap switch by means of a simple lever arm
Applications
- Protects pumps, motors and other equipment against low or no flow
- Controls sequential operation of pumps
- Automatically starts auxiliary pumps and engines
- Stops liquid cooled engines, machines and processing when coolant flow is interrupted
- Shuts down burner when air flow through heating coil fails
- Controls dampers according to flow
