A ball valve is a device with a spherical closure
unit that provides on/off control of flow. The sphere has a port, also known as
a bore, through the center. When the valve is positioned such that the bore is
aligned in the same direction as the pipeline, it is in open position and fluid
can flow through it. When rotated 90 degrees, the bore becomes perpendicular to
the flow path, meaning the valve is closed and the fluid cannot pass through.
The ball valve, along with butterfly and plug
valves, is part of the quarter-turn valve family. Ball valves are known for
reliable, bubble-tight sealing. Thus, they are a great choice for gas
applications where tight shutoff is necessary. Due to the potential of constant
wearing on the seats, ball valves are not ideal for throttling applications.
The body of a ball valve usually is made of steel and can be made more durable
with nickel plating.
The most common ball valves are considered to be
two-way, which allows flow to travel linearly from the inlet to the exit.
Furthermore, the three-way and four-way ball valves allow for flow to travel in
multiple directions, including 90-degree angles.
There are four general body styles of ball
valves: fully welded, three-piece body, split-body, and top-entry. The
difference is based on how the pieces of the valve are manufactured and
assembled, but the valve operation is the same in each type. Each design has
its benefits.
Applications:
Ball valves can be used in a variety of
applications and markets, such as transmission and storage, gas processing,
industrial, and many more. Ball valves have low pressure drop and can open and
close quickly. SIO specialize in the ballvalves manufacturing and design widely used in oil and gas, chemical,
power, mining, water treatment and general industrial systems.
SIO mission is to design, manufacture, and supply
high added value valve products, managing the projects in an honest way for our
customers, people and environment.
