The nominal capacity is based on the following conditions:
Refrigerant Evaporating temperature Condensing temperature Subcooling Pressure Drop Isentropic Efciency
R-22, R-404A, R-507 +40°F +100°F 2°F 2 psid 80%
R-407C +40°F bubble point +100°F dew point 2°F 2 psid 80%
Remarks: Bi-ow versions are not released for hot gas ow applications.
EX6, EX7 and EX8 must be installed with motor downward in suction line applications.
This insures the valve life expectancy.
