i have a pressure control valve which is for keeping pressure at its downstream to 350 psig and is sized for 22 mmscfd flow
the pressure at inlet in normal operation is 400 psig
however, lets say in a case the pressure at inlet is < 350 psig,,,,in that case will the control valve go maximum or fully open?
the cases for control valve sizing are:
max 22 x 1.1 = 24.2 mmscfd, pinlet = 400 psig, poutlet = 350 psig
normal 22 mmscfd, pinlet = 400 psig, poutlet = 350 psig
min 22 x 0.5 = 11 mmscfd, pinlet = 400 psig, poutlet = 350 psig
in case we encounter a flow lower than 11 mmscfd at inlet, what will be the impact on control valve
