why the positioner output is 3-15psi

Answer Posted / ch amir islam

Normally we use the CVs that have thier bench set more than
3 to 15 PSI but some time at low pressure line we use CVs
that have bench set of 3 to 15 PSI so we use the i/p of a
possitioner as o/p for traveling of CV but in normal cases
we dnt have i/p of possitioner below than 15 PSI.
