Answer / kuber
The pressure will be proportional to the flow rate, as the
flow rate increases the pressure at inlet of the valve will
increase. then the valve starts to close relatively.

Answer / r.murugan
if pressure transmitter installed before pcv (example sp
10bar) suddenly pipe line flow increase pressure will
increase but as long as controller an auto controller will
give command to open the valve to maintain the setpoint pressure
if flow rate is less pressure is coming down less than
setpoint controller will give command to close the valve to
maintain the pressure (if pressure tapping before control
valve)

Answer / triptisliet@gmail.com
according to bernauli's theorem total enerngy will remain
same so if velocity increases then pressure decreases.

Answer / tony lorenzo
If the controller is in Auto that time, and provided its been tuned, the pressure should remain as is. The PCV valve should open as expected, how much? we dont know.
