Can anyone help me with this valve please?
Hi Everyone,
Called to a system today which is showing all the signs of pumping down on the TEV.
Its a Danfoss on R404, multideck 4-5c set point.
I've checked the strainer and it's fine.
Does anyone know if these fail in such a way that this is possible, if the phial loses its charge or some kind of mechanical defect?
Thanks.
