Hi There,
I didn't see any ARC (Automatic Recirculation) valves used for pump minimum flow protection until the recent project. People put a couple of ARC valves on pump discharge side for pump minimum flow protection. I used to see FE/FV combinations instead.
Is it a good practice to use this kind of valves? It appears to be cheaper. Rather than this, any advantages / disadvantages based on your experience?
Regards,
Leo
