Dwyer V4-SS-2-D-U Flow Switch, Universal Vane, 316SS DPDT

Downloads: datasheet manual

Leak proof body machined from bar stock. Weatherproof, designed to meet NEMA 4.

Features

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
