5 Great Ways To
Think About Choosing A Valve
If the liquid you were working with was at the ideal temperature,
within the perfect range of pressure and unlikely to damage
anything if it leaked, only one valve would exist in the world!
However, real life is rarely that simple. All liquids come with
issues. And to process them you need to know how they work.
Therefore, choosing a valve for your application is an important
task, one that involves advanced knowledge on how pumps work
and what the properties of the liquid you need to move are.
An appropriately selected valve (or indeed any piece of equipment
that comes into contact with fluid) can mean efficiency, safety,
Here Are Five Things
To Think About When Selecting Valves.
1. Think about conditions
Be aware of your process conditions while choosing a valve.
What are the properties of the liquid you're pumping? Are there
any compatibility issues that will impact the material selection
of your pipes, pumps, and valves? Do you need a large capacity?
Certain types of valves are better suited to that than others.
Is your liquid extremely viscous? Is the moving substance a
gas that can be compressed? Is it a control valve? Will it be
closed or open? Is 2-way or more? All that impacts choice. So
as we've said before and we'll say again, know your playing
field and that knowledge will enable the ideal selection.
2. Think about space
Process systems are typically large because the valve itself
is only one component, which comes with a lot of piping and
fittings. Depending on whether your pipes are welded, flanged
or threaded, and how many Us, Ls and T shapes you have, the
amount of space you need will vary. While this means a lot of
thinking about the materials of your equipment and the way in
which they are put together, it also means you need to have
the space to put it in the ideal configuration for efficiency.
3. Think about speed and efficiency
Everything today happens fast. This means automation. While
cost benefits might point you towards manual options, remember
that will impact your ability to react quickly to changes in
conditions including temperature, pressure, and flow. Today's
valves have automated control devices that can even be operated
remotely. See if that makes sense for your business.
4. Think about back-ups and fail-safes
Once you've made a selection, despite proper planning and testing,
things can go wrong in sensitive applications. Power outages,
wear and tear, operator inexperience, forces of nature (like
water damage or tiny critters chewing on your wires). The things
that could go wrong are endless. Putting in place backup power
and having a disaster mitigation plan to ensure these things
don't impact your bottom line is one aspect. The other is thinking
about your environment to see if you need a valve that comes
with some fail-safes to give you additional control.
5. Think about getting expert advice
There are many options and configurations available and sometimes
picking one can seem pretty daunting. While the points above
can help you think about your unique set of conditions, there's
no shame in bringing in people to offer you an advisory service.
Many vendors will be able to review your applications and make
appropriate recommendations for little or no extra charge.
