(Rating conditions for liquid refrigerant based on a flow of 3.9 lbs/min/ton of refrigeration with a 2-PSI
pressure drop across the valve, a condensing temperature of 100°F, and a suction temperature of 40°F.
Rating conditions for refrigerant gas based on a flow in CFM of refrigeration with a 5 PSI pressure drop
across the valve, a condensing temperature of 100°F, gas with a 20°F superheat entering the valve, an
evaporator temperature of 40°
