TXV selections are based on +25°F suction temperature, 10°F T.D., and 95°F liquid temperature,
105°F Condensing temperature and high side pressure drop of 10 PSIG.
NOTE 2: For R-507, replace the second ‘S’ with ‘P’ in R-404-A TXV. For example,
SBFSE-B-C (R- 404A)
becomes SBFPE-B-C and EGSE-1-1/2-C becomes EGPE-1-1/2-C (R-507)
For R-449A, use the same TXV as R-448A
For R-407F, use the same TXV as R-407A
