According to flapper nozzle system, the flapper nozzle gap
and output of back pressure is nonlinear.But if we observe

Answer / poorni

we cant find the error wnen it is in null conditions.so the

does not exist more than 15 psi.

Answer / 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.
