Ristriction Orifice in Control Valve ByPass
Ristriction Orifice in Control Valve ByPass
(OP)
Hi Every Body
In BFW Services (Inlet Pressure:74 Barg, Desired Discharge Pressure:20 Barg) Due to Control Valve Bypass valve Failure and Leakage, it seems that we must install Ristriction Orifice in bypass line of Control Valve. I want to know that Is it possible or Allowable to install Restriction orifice in control valve bypass line?

The problem with installing a restriction orifice is that when the flow is zero then so is the pressure drop, and you will have the full pump pressure exerted on the control valve. In general I do not like to put ROs in series with valves.
