I want to control remotely a bypass por a water softener.
The bypass is installed on 22mm copper pipe and the water pressure is 3 to 4 bar.
I am looking for a three port motorized valve like the Honeywell V4073A1039 model where port B is normally closed and port AB is normally open.
I want the valve with the lowest pressure drop (even if that requires a bigger than 22mm valve)
Is there a motorized valve that works like I describe and that is more suited for my needs?
Alternatively, I would have to used two one port motorised valves. One normally open and one normally close, but I think this would not be as practical.
Thanks,
Antonio
