Isolation Valve on oil/water bridle
Isolation Valve on oil/water bridle
(OP)
How much is it important to have isolation valves on the main lines feeding the bridle on which level switches and LG are installed which have their own isolation valves.
Plant operation reasons out that since the liquid in the bridle remain stagnent therefore becterial growth causes corrosion and that is why recent leak in the bridle has occured. It is to note that the bridle has a 1/2" vent and 1/2" drain.
I agree to the point that it is a good engieering practice to have isolation valves for maintenance ease but the captioned logic does not click.
Your expert opion will add to my knowledge.

In my case where the existing system has all the switches on the bridle, I was little hasitant to install isolating valves just because of the reason you mentioned.
However, Saxon's point has some weight and should be given due consideration unless there is some other complling reason not to install isolating valves.
Any way you have highligted a good point, thanks for the input
