Problems with the installation of flow control orifice plates
Thread Content
What is the impact of installing a flow control orifice plate downstream of the shut-off valve and directly between the flanges?
In my opinion, it is necessary to clarify the main function of the flow-limiting orifice plate.
The flow-limiting orifice plate is primarily used to prevent hydraulic imbalance in the system caused by excessive flow in the branch lines, thereby imposing restrictions; it also serves to protect the flow meter from operating outside its range. On the forum, there are posts that explain the working principle of flow-limiting orifice plates, which can be used as a reference.
It seems to be installed in front of the cut-off valve, generally
