Table 3: The equivalent cooling capacity values in the table refer to a liquid temperature at the valve inlet = 38°C. For temperatures other than 38°C, in the table identify the
valve with the equivalent capacity RATING that is higher than or equal to the required rated cooling capacity CAP multiplied by the coeffi cient shown in Table 2. To allow for any
uncertainty in the design data, the values in the tables correspond to 80% of the maximum effective cooling capacity .
