High performance pinch valve for abrasive,
corrosive slurries relies on fast-acting control
Requirement
Pinch valves control the volume of fluids
flowing through pipes for batching
processes in mining operations. They
are also used to isolate slurry or dirty
water from the process. Flowrox Group,
headquartered in Finland, is the leading
supplier of high performance pinch
valves and other equipment for mineral
processing. Flowrox pinch valves are
ideal for shut-off or control applications
that involve abrasive or corrosive
slurries, powders or granular
substances. Their customer wanted
fast-acting control that could actuate the
pinch valves in just a few seconds.
Flowrox turned to Norgren, now IMI
Precision Engineering, for a control
valve that could meet this requirement
by moving a large amount of
compressed air in a short time.
Solution
With a flow coefficient of 5.0 and compact
size, the IMI Norgren Nugget 500 valve
allows Flowrox to meet their customer's
requirement. In addition to increasing
controllability, the fast-acting valve allows
operators to close down the process
quickly in an emergency. The Nugget 500
has nitrile O-rings and seals so it can
operate reliably across a broad
temperature range. Its durable finish
provides excellent corrosion and chip-
resistant protection so it stands up to the
harsh operating conditions typical of
processing plants at mine sites. The
Flowrox pinch valve is ideal for this
mining application because of its
excellent wear and corrosion resistance
and ability to operate without jamming or
clogging for extended service intervals.
