Quizix's pumps required valves that
can handle corrosive fluids at high pressures
for millions of cycles.

The Challenge
Quizix, Inc., based in North Highlands,
CA, is a leading manufacturer of precision fluid-handling equipment,
such as high-performance pumps. First used in oil field research,
Quizix's pump systems arer now employed in production environments
around the world where precise flow rate or volume measurement
is critical.
Quizix recently needed to develop
an automated valve that could operate for 10 million cycles. They
needed to design a valve that was remotely actuated, didn't change
volumes, and could work as long as needed.
Quizix engineers determined that the
best design for the job was an annulus structure: one cylinder
nested inside another. Quizix's challenge was to optimize the
size and shape of the annulus to get the largest CV possible.
The CV is defined as the number of gallons per minute of water
that will flow through a structure with one PSI (pound per square
inch) drop across it. Any pressure loss at either end of the valve
would ultimately lower the CV.
The Solution
With the easy integration between COSMOSFloWorks and their SolidWorks
3D CAD software, it seems almost natural that Quizix chose COSMOSFloWorks
to add as their analysis package. "We were up and running
analyses on our SolidWorks designs in no time," says John
Petro, president of Quizix.
Using COSMOSFloWorks, the engineers
were quickly able to analyze the design and determine that the
function was similar to a decaying exponential curve.
"COSMOSFloWorks accurately predicted
that the valve wasn't linear," said Petro, "With this
finding in hand, we picked the best operating point on the curve
- the point that minimized the pressure drop and maximized the
CV for that annulus in record time."
Summary and Metrics:
- Reduced analysis time from days to minutes.
- Increased critical flow coefficients by 50% without adding
to the cost.
- Reduced physical prototypes.

"The
software essentially paid for itself because we no longer
have to spend time developing expensive prototypes and
continually redesigning products. COSMOSFloWorks enables
us to design and build products right the first time."
John Petro, President.
