V8 Flotect®
Flow Switch Protects Equipment: 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 motor, pump, engine, etc. 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 a 1 inch through 6 inch pipe.
Operating pressures are up to 150 psig (10 bar) and temperatures
to 212°F (100°C). The V8 flow switch can be used in various
chemical processes, industrial systems and similar applications
where process conditions are compatible with polyphenylene
sulfide, ceramic 8 and 316SS. The V8 Flotect® flow switch
is UL recognized as an industrial motor controller per UL
standard 508, suitable for mounting in a protected environment.
APPLICATIONS
Applications are chemical processing, air conditioning,
refrigeration, heating systems, cooling lines, machinery,
liquid transfer systems, water treatment, food processing,
and machine tools. Also, other applications compatible with
the materials of construction.
