What valve would this be... it was found on a unit used to quick-chill chocolate in a cooling tunnel. There has been some discussion on it, it was found in the suction line between the compressor inlet and the evaporator outlet. The valve was fed directly off the liquid line and when open it apparently fed the liquid straight into the suction line. Everyone is of the opinion that it was to desuperheat the suction gas possibly but the operation of the valve "ORO" was the confusing part along with its application. Ever heard of it??
