Application:
Metering device for
IV fluid flow
Products: 3/16" Precision
glass balls
Benefits: Lower cost,
reduced weight
In this application, a 316 stainless
steel ball was originally used.
It offered excellent corrosion
resistance and strength for the
application and was readily
available. Because of the
minimal requirement for strength,
however, it was determined that a
precision glass ball could be used
instead.
Glass offered high corrosion
resistance, more than adequate
strength, lower cost, and was
approximately one-third the weight.
The finish of the ball was a ground
finish to ensure the product would
be visible during the assembly
process.
