globe valve with spool blind query
(OP)
Dear Sir/Madam
I attached part of the P&ID from my project.
Could anyone kindly tell why is the valves and blind flanges set there together? Is any reason behind this?
Thank you so much.

We have many of these around our facility, in fact we have this arraignment on all of our plate heat exchangers for ease in the cleaning and changing gaskets.

You should find and study the "Legend" Sheet that normally is included with any set of P&IDs.
A. I think that the valve you are concerned about is a "Ball" Valve not a Globe Valve.
B. The "Spec Blind" at the Drain valve is installed in the closed position.
C. The "Spec Blind" in the Incoming Feed line is installed in the open position.
