Dear experts, on the diagram of the turbine emergency shutdown valve, what pressure is being measured by the pressure gauge marked with a red circle? What is its function?

I see that the plug is used to block it on the drawing, yet a pressure gauge is installed on the quick-close valve. I would appreciate it if experts could help explain this.
Pressure gauges are generally installed on the cylinder head. Why are they placed there? No blueprints?
There are drawings, and the plugs used in those drawings are in place to block things.
This is the pressure measurement interface for the pressure gauge; it is installed as per the owner’s requirements and is prepared during the design and manufacturing process.
Based on the position of the diagram, it should be the quick-shut oil pressure. It’s usually a side test pressure gauge, which is installed on the outermost side of the cylinder and has a designated port.
Is there pressure here? ? ? ? ? ?
It was installed in the wrong position; there is a plug in the middle of the quick-close valve cover, which is the designated port for installing a pressure gauge.
In my opinion, it is used to measure the \"jump-out oil pressure\" (or speed-shut oil pressure). As for the fact that the diagram shows a plug, it doesn’t matter!
This area should be the drain port for leakage from the packing seal.
