, INTRODUCTION
Valve is a device that controls the flow of a fluid by
opening, closing or regulating the various
pathways.
Used to control flow, rate, volume, pressure and
the direction of fluid within a pipe.
Applications include industries, transportation,
commercial, military etc.
Oil and gas, power generation, mining, sewerage,
chemical manufacturing constitute majority of
industrial valves.
BACK
, INTRODUCTION
Valves can turn on or off, regulate, modulate, or
isolate.
They can handle temperatures from the cryogenic
region to molten metal exceeding 1500°F, and valves
can contain pressures ranging from severe vacuum
to 20,000 pounds per square inch.
Range in size from a fraction of an inch to as large as
30 feet in diameter
Valves also can control the flow of all types of
commodities from the thinnest gas to highly
corrosive chemicals, from superheated steam to toxic
gases, from abrasive slurries to radioactive materials
