Check valve
Dear Friends,
Would you please help me to understand reason of this installation ? "Installing a check valve beside of a ball valve" for why ?
See my photo.
Thanks.

Re: Check valve
Possibly to relieve any overpressure that may occur within the section that could be valved off but still contains liquid.

Re: Check valve
Hi
it is check valve .
when you want to replace core inside filter you close inlet valve and outlet valve in filter.
then you pour hot water on core dryer .
all liquid comes to gas and goes back by check valve to condenser side ,so you save a lots of refrigerant liquid
