Pinch valve is widely accepted
as designs suited to industrial, municipal and mining services where abrasive,
corrosive, scale or plugging prone slurry, sludge, liquid or bulk solids
are processed. Pinch valves offer a cost-effective alternative to
metal alloy, lined, or coated ball, plug, gate, and diaphragm valves that
do not offer comparable mechanical advantage, chemical resistance,
leak tight shut-off, or 100% full flow.
Pinch valves offer a wide range of design, performance, quality and
service capabilities. Pinch valve manufacturers sell in their domestic markets
also the global market. As in cases of all valves, a thorough
understanding of process conditions is essential to selecting the correct
pinch valve elastomer tube (also referred to as rubber sleeve
or rubber muff) to obtain full value and longevity from this versatile
with Pinch valves arise, it is only due to elastomer
failure as the rubber sleeve is stretched and stressed during closure.
This often results in the cutting of the rubber sleeve around the pinch
area, or incomplete closure resulting in high velocity wear and shortened
sleeve life. In some cases, users are simply unaware that specialized
constructs with good / double reinforcement are required for negative pressure/vacuum
conditions/good life of sleeve and avoid pump damage from sleeve collapse
on suction side.
in Pinch valve rubber sleeve resistance to abrasion, chemicals, corrosion, temperature, as
well as significant improvements in pinch valve design technology, have
expanded the applications with the introduction of high-quality pinch
valves. One of the reasons for increased usage is the availability of
automatic pinch valves- Gear operation, Electrical actuation, pneumatically operated On/Off and throttling
control valves. Pinch valve users are no longer limited to non-standard
face-to-face designs that make maintenance problematic and restrict wider
use replacing other conventional valves. Other improvements include the ability to
detect sleeve wear as well as redesigned rubber sleeve with
reinforcement that ensure higher cycles and extended sleeve life.
Specialized constructs also allow for operation on the suction side of a
pump and in vacuum conditions without collapse.
For pinch valve, the initial purchase price is just one portion of the
total ownership cost. As erosive and corrosive media wear the rubber
sleeve / liner / muff / tube, it must eventually be replaced. Elastomer quality,
price, and frequency of rubber sleeve replacement are a major component of
life-cycle costing, as are direct and indirect costs of valve removal and
reinstallation, time, repair,
product loss, contamination, clean up, and other factors per incident.
Accordingly, paying a bit more for quality at the outset can often be
recouped in less than a year by simply avoiding the cost of one
