Restriction Orifice Valve

[ChoiWooSeon]

Hello. Engineer guyz. Thank you for your kind reply and cooperation for our queries.
Have you guyz experienced to take account into the 'restriction orifice valve' within RFCC System (Axen License)?
please, refer to below captured figure and P&ID. I don't have any experience for this item.
If you guyz have any information, Please let me share that.

1) Can we change the logic of valve from 'restriction orifice valve' to "Gate valve + Restriction Orifice" ?
2) I want to know why this item should be used in this process.

For question 1) No. For question 2) See note A. ". . . [Restriction orifice] will be open[ed] to allow operator for (sic) additional flexibility (line unplugging)".

If you want to make the orifice permanant, as you describe, you will want to add another means for "line unplugging."



I used to count sand. Now I don't count at all.
