Users of pneumatic valve positioners
can now assess the energy efficiency
of their valve installations with a new
calculator from ABB. Based on the
amount of compressed air consumed
by conventional positioners, the
calculator shows how using the latest
smart positioner technology can help
operators reduce their energy costs.

The calculator uses details including
the number of pneumatic positioners
on site, air cost per standard cubic
foot and the percentage of time
spent at a steady state to calculate the
user’s current compressed air energy
costs. These costs are then compared
to the potential savings that could be
achieved using ABB’s TZID-C
intelligent positioners, where
compressed air is only consumed
when required.
