• A certain process requires that the fluid that enters is variable according
to certain conditions.
• The entry and exit speed must be different between the two points.
• You require having absence of flow in some parts of the system to give
maintenance or others.
• You want to increase or decrease the pressure between two points.
However, the main basis is the variability in the state of the flow entering and
leaving the system.
You must use them when variable conditions are required over time and related
to the fluid that we handle in the system. "
How is a valve installed, and where should it be placed?
The installation of a valve is variable and depends on the type of valve. Each
supplier has its technical specifications that guarantee the correct installation
and operation of these instruments. It is correct to seek advice and leave the
installation of valves in the hands of someone trained. However, some general
considerations will be described below:
Some valves in your installation will require the use of flanges, while others
may be welded. As a general criterion, a valve being a control element must not
be installed where control cannot be exercised. That is, if you install the valve in
an inaccessible place where no one can manipulate it, then the control you have
over your process will be restricted by the location of the valve. Another
element to consider is the maintenance or future replacement of the valve. If
you leave the valve fully fixed without the possibility of being removed, you
will be limiting maintenance work and process improvement, causing more
problems than solutions.
Considering the technical specifications of the valve will prevent the instrument
from being damaged prematurely, respecting the safety and health regulations
also contributes to the correct installation and operation of the valve. You must
make sure that before starting the valve, its assembly is correct; this means that
the shafts are perfectly aligned, otherwise it may cause serious mechanical
problems in it.
